  1. There are other factors that cause motor vibration and noise!
    Axial vibration and noise of end caps
    The axial vibration of the end cover is 1 of the sources of mechanical noise, which is mainly excited by the bearing vibration, which is more important in small motors. The smaller the axial dynamic stiffness of the end cover, the easier it is to excite larger vibration speed and noise.

    Vibration and noise of the brush unit

    The vibration and noise of the brush device are caused by the poor surface condition of the commutator, the large gap between the brush and the brush holder, the small brush pressure or the improper pressure application which makes the brush skew, and the brush holder, brush holder and brush rod. It is caused by structural and technological reasons such as insufficient stiffness.

    When the DC motor is running, the sliding contact condition of the brush and the commutator, as well as the cuprous oxide film formed on the surface of the commutator and a layer of graphite film and dust particles covered on it, not only affect the commutation performance of the motor, but also affect the commutation performance of the motor. to vibration and noise.

    Practice has proved that due to the low temperature of the sliding contact surface at no load, the above-mentioned film is not easy to form, and the dry friction between the brush and the commutator increases the noise. For example, when the no-load operation cycle of the rolling DC motor accounts for more than 50% of the total time, the noise under no-load conditions is 6~10dB higher than that under load. This vibration is different from the vibration of the commutator surface due to mechanical reasons, which can be detected when the motor is running at low speed (vibration is felt when the brush is touched by hand). The frequency spectrum of brush vibration noise generated by sliding contact is generally in the range of 1000~-8000Hz, and it does not change much when the motor speed changes, which is 1 of the characteristics that distinguish it from mechanical reasons.

    The brush vibration noise produced by the sliding contact is also related to the brush polarity. For example, the positive brush of a DC generator has less vibration than the negative brush; because the positive brush can separate graphite and carbon crystals, absorb moisture on the surface of the commutator to form a lubricating film, and the negative brush removes it. The formation of the sliding contact film is also related to the grade of the brush. The selection of the grade is first to ensure good commutation performance, but at the same time, the vibration and noise of the brush should also be considered.

    In addition to mechanical noise, aerodynamic noise is also a major problem in motor noise control. Especially for high-speed motors, this problem is relatively concentrated. In the tweet after bearing, Ms. participated in the meeting and chose some content to share with you.

How are servo motors used in CNC machines and other precision machining equipment?

Servo motors play a crucial role in CNC (Computer Numerical Control) machines and other precision machining equipment. They provide precise and dynamic control over the movement of various axes, enabling high-accuracy positioning, rapid speed changes, and smooth motion profiles. Here’s a detailed explanation of how servo motors are used in CNC machines and precision machining equipment:

1. Axis Control:

CNC machines typically have multiple axes, such as X, Y, and Z for linear movements, as well as rotary axes for rotational movements. Servo motors are employed to drive each axis, converting electrical signals from the CNC controller into mechanical motion. The position, velocity, and acceleration of the servo motors are precisely controlled to achieve accurate and repeatable positioning of the machine’s tool or workpiece.

2. Feedback and Closed-Loop Control:

Servo motors in CNC machines are equipped with feedback devices, such as encoders or resolvers, to provide real-time information about the motor’s actual position. This feedback is used in a closed-loop control system, where the CNC controller continuously compares the desired position with the actual position and adjusts the motor’s control signals accordingly. This closed-loop control ensures accurate positioning and compensates for any errors, such as mechanical backlash or load variations.

3. Rapid and Precise Speed Changes:

Servo motors offer excellent dynamic response, allowing CNC machines to achieve rapid and precise speed changes during machining operations. By adjusting the control signals to the servo motors, the CNC controller can smoothly accelerate or decelerate the machine’s axes, resulting in efficient machining processes and reduced cycle times.

4. Contouring and Path Tracing:

CNC machines often perform complex machining tasks, such as contouring or following intricate paths. Servo motors enable precise path tracing by accurately controlling the position and velocity of the machine’s tool along the programmed path. This capability is crucial for producing intricate shapes, smooth curves, and intricate details with high precision.

5. Spindle Control:

In addition to axis control, servo motors are also used to control the spindle in CNC machines. The spindle motor, typically a servo motor, rotates the cutting tool or workpiece at the desired speed. Servo control ensures precise speed and torque control, allowing for optimal cutting conditions and surface finish quality.

6. Tool Changers and Automatic Tool Compensation:

CNC machines often feature automatic tool changers to switch between different cutting tools during machining operations. Servo motors are utilized to precisely position the tool changer mechanism, enabling quick and accurate tool changes. Additionally, servo motors can be used for automatic tool compensation, adjusting the tool’s position or orientation to compensate for wear, tool length variations, or tool offsets.

7. Synchronized Motion and Multi-Axis Coordination:

Servo motors enable synchronized motion and coordination between multiple axes in CNC machines. By precisely controlling the servo motors on different axes, complex machining operations involving simultaneous movements can be achieved. This capability is vital for tasks such as 3D contouring, thread cutting, and multi-axis machining.

In summary, servo motors are integral components of CNC machines and precision machining equipment. They provide accurate and dynamic control over the machine’s axes, enabling high-precision positioning, rapid speed changes, contouring, spindle control, tool changers, and multi-axis coordination. The combination of servo motor technology and CNC control systems allows for precise, efficient, and versatile machining operations in various industries.

Can you explain the concept of torque and speed in relation to servo motors?

Torque and speed are two essential parameters in understanding the performance characteristics of servo motors. Let’s explore these concepts in relation to servo motors:


Torque refers to the rotational force produced by a servo motor. It determines the motor’s ability to generate rotational motion and overcome resistance or load. Torque is typically measured in units of force multiplied by distance, such as Nm (Newton-meter) or oz-in (ounce-inch).

The torque output of a servo motor is crucial in applications where the motor needs to move or control a load. The motor must provide enough torque to overcome the resistance or friction in the system and maintain the desired position or motion. Higher torque allows the motor to handle heavier loads or more challenging operating conditions.

It is important to note that the torque characteristics of a servo motor may vary depending on the speed or position of the motor. Manufacturers often provide torque-speed curves or torque-position curves, which illustrate the motor’s torque capabilities at different operating points. Understanding these curves helps in selecting a servo motor that can deliver the required torque for a specific application.


Speed refers to the rotational velocity at which a servo motor operates. It indicates how fast the motor can rotate and how quickly it can achieve the desired position or motion. Speed is typically measured in units of revolutions per minute (RPM) or radians per second (rad/s).

The speed of a servo motor is crucial in applications that require rapid movements or high-speed operations. It determines the motor’s responsiveness and the system’s overall performance. Different servo motors have different speed capabilities, and the maximum achievable speed is often specified by the manufacturer.

It is worth noting that the speed of a servo motor may also affect its torque output. Some servo motors exhibit a phenomenon known as “speed-torque curve,” where the motor’s torque decreases as the speed increases. This behavior is influenced by factors such as motor design, winding resistance, and control algorithms. Understanding the speed-torque characteristics of a servo motor is important for selecting a motor that can meet the speed requirements of the application while maintaining sufficient torque.

Overall, torque and speed are interrelated parameters that determine the performance capabilities of a servo motor. The torque capability determines the motor’s ability to handle loads, while the speed capability determines how quickly the motor can achieve the desired motion. When selecting a servo motor, it is essential to consider both the torque and speed requirements of the application to ensure that the motor can deliver the desired performance.
