Matters needing attention

Oil and water protection of servo motor

1) The servo motor can be used in the place that will be attacked by water or oil drops, but it is not completely waterproof or oil-proof. Therefore, the servo motor should not be placed or used in the environment of water or oil invasion.

2) If the servo motor is connected to a reduction gear, the oil seal should be filled when using the servo motor to prevent the oil of the reduction gear from entering the servo motor

3) The cable of servo motor should not be immersed in oil or water.

Servo motor cable → stress relief

1) . ensure that the cable is not subjected to moment or vertical load due to external bending force or its own weight, especially at cable outlet or connection.

2) When the servo motor is moving, the cable (that is, the one configured with the motor) should be firmly fixed to a stationary part (relative to the motor), and an additional cable installed in the cable support should be used to extend it, so that the bending stress can be minimized.

3) The elbow radius of the cable should be as large as possible.

Allowable shaft end load of servo motor

1) . ensure that the radial and axial loads applied to the servo motor shaft during installation and operation are controlled within the specified values of each model.

2) . be careful when installing a rigid coupling, especially excessive bending load may cause damage or abrasion to the shaft end and bearing.

3) It is better to use flexible coupling to make the radial load lower than the allowable value, which is specially designed for servo motor with high mechanical strength.

4) For permissible axle load, please refer to "permissible axle load table" (instruction manual).

Installation of servo motor

1) When installing / removing the coupling parts to the shaft end of the servo motor, do not directly hit the shaft end with a hammer. (when the hammer strikes the shaft end directly, the encoder on the other end of the servo motor shaft will be damaged.)

2)Try to align the shaft end to the best condition (improper alignment may cause vibration or bearing damage).

Performance comparison between servo motor and stepping motor

As an open-loop control system, stepping motor has essential connection with modern digital control technology. In the current domestic digital control system, stepping motor is widely used. With the emergence of all digital AC servo system, AC servo motor is more and more used in digital control system. In order to adapt to the development trend of digital control, stepping motor or full digital AC servo motor is mostly used as the executive motor in motion control system. Although they are similar in control mode (pulse train and direction signal), they are quite different in performance and application. This paper compares the performance of the two.

The main difference between brushless DC motor and DC servo motor

Different definitions: (1) Brushless DC motor is a typical mechatronics product, which is composed of motor body and driver. Brushless motor refers to the motor without brush and commutator (or collector ring), also known as commutator less motor. As early as the 19th century, when the motor was born, the practical motor was the brushless form, that is, the AC squirrel cage asynchronous motor, which has been widely used. However, the asynchronous motor has many insurmountable defects, so that the development of motor technology is slow. The transistor was born in the middle of last century, so the brushless DC motor using transistor commutation circuit instead of brush and commutator came into being. This new type of brushless motor is called electronic commutation DC motor, which overcomes the defects of the first generation of brushless motor.

Basic principle and optimization algorithm of BLDC

Brushless direct current motor (BLDCM,) gets rid of the inherent shortcomings of the brushless DC motor, and replaces the mechanical motor rotor with the electronic motor rotor. Therefore, the brushless DC motor not only has the excellent speed characteristics of the DC motor, but also has the advantages of simple structure, no commutation flame, reliable operation and easy maintenance.

Working principle of servo motor (how servo motor works)

The rotor inside the servo motor is a permanent magnet. The U / V / W three-phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the effect of this magnetic field. At the same time, the encoder of the motor feeds back the signal to the driver. The driver adjusts the rotation angle of the rotor according to the comparison between the feedback value and the target value. The accuracy of servo motor depends on the accuracy of encoder (number of lines).

The internal structure and characteristics of the micro servo motor

A miniature servo motor includes a small DC motor, a set of variable speed (reduction) gear sets, a feedback adjustable potentiometer and an electronic control board. Among them, the high-speed rotating DC motor provides the original power and drives the variable speed (reduction) gear set to produce a high torque output. The greater the gear ratio of the gear set, the greater the output torque of the servo motor, that is to say, the greater the weight it can bear, the lower the speed of rotation it will be.
