Estun Servo Motor – The difference between a servo motor and a stepper motor

Servo drive is a kind of controller used to control servo motor, its function is similar to that of an inverter acting on an ordinary AC motor, which is a part of the servo system and is mainly used in high-precision positioning systems. Servo drive is an important part of modern motion control, which is widely used.

structure AC servo motors are usually single-phase asynchronous motors, with two structural forms: squirrel cage rotor and cup rotor. Like ordinary motors, AC servo motors are constructed of a stator and a rotor. There are two windings on the stator, namely the excitation winding and the control winding, and the two windings are ...

1. The electromagnetic torque of the synchronous motor is the interaction between the rotating magnetic field of the stator generated by the power supply voltage and the main magnetic field of the rotor; 2. The intersection angle of the magnetic pole axis of the rotating magnetic field of the stator and the main magnetic field of the rotor is called the work angle; 3. When the power angle is zero, the electromagnetic torque is zero, and the work is zero.

The servo control system is an operating system that can automatically control the mechanical movement of the test device according to the predetermined requirements. There are many classification methods for servo systems, and there are three common classification methods: 1. Classification according to the characteristics of the controlled parameters. 2. According to the type of drive element ...

The daily inspection is mainly to monitor the start-up and operation of the motor, find abnormal phenomena in time, and prevent accidents. Generally, it is carried out by looking, hearing, touching, smelling, asking and monitoring the ammeter and voltmeter. (1) Observe whether the motor has abnormal noise and vibration. Especially...

First, the control accuracy is different The step angle of the two-phase hybrid stepper motor is generally 3.6 ° and 1.8 °, and the step angle of the five-phase hybrid stepper motor is generally 0.72 ° and 0.36 °. There are also some high-performance stepper motors with smaller step angles. Such as Sitong company produced a kind of wire for slow wire ...

16. Is it safe to use a DC power supply voltage greater than the rated voltage value to drive the motor? Normally this is not a problem, as long as the motor is operating within the set speed and current limits. Because the motor speed is proportional to the motor line voltage, choosing a certain supply voltage will not cause ...

AC servo motor (1) Cage type two-phase AC servo motor (slender cage rotor, mechanical characteristics are approximately linear, small volume and excitation current, small power servo, low-speed operation is not smooth enough) (2) Non-magnetic cup rotor two-phase AC servo motor (coreless rotor, mechanical ...

1. The motor cannot rotate after being energized, but there is no abnormal noise, no peculiar smell and smoke. 1. Cause of failure: (1) The power supply is not connected (at least two phases are not connected); (2) Fuse blowing (at least two-phase blowing); (3) The overcurrent relay is adjusted too small; (4) The wiring of the control equipment is incorrect. 2. Failure ...

Stator windings are short-circuited between phases or turns 6. Stator winding grounding 7. The power supply voltage is too high ...

A servo control system is a feedback control system that is used to accurately follow or reproduce a process. In many cases, the servo system refers specifically to the feedback control system in which the controlled quantity (the output of the system) is the mechanical displacement or displacement velocity and acceleration, and its function is to make the mechanical displacement of the output (or ...

Precautions for servo motors: 1. Protection of servo motor oil and water A: The servo motor can be used in places where it will be attacked by water or oil droplets, but it is not fully waterproof or oil-proof. Therefore, servo motors should not be placed or used in water or oil-infested environments. ...

The selection of servo motor is not only affected by the weight of the mechanism, but also the movement conditions of the equipment will also change the selection of servo motor. The greater the inertia, the greater the acceleration and deceleration torque, and the shorter the acceleration and deceleration time, the greater the output torque of the servo motor. When choosing a servo motor specification, follow the steps below. ...
