What are the internal rotors of servo motors?
The internal rotors of servo motors are permanent magnets. The so called permanent magnets refer to those magnets that have unchanged magnetic poles and magnetic field strength. Servo motors mainly used arc magnets, just as below pictures:
Here is some information of servo motors magnets.
1、Do the rotor magnets of servo motors need adhesive?
The rotor magnets must need adhesive. There are many types of adhesive, such as KR series of high temperature resistant adhesive, AB adhesive and so on.
2、Why can't we use electromagnets to replace permanent magnets as the rotors?
Some netizens might reply that the electricity needs money, and in a finite electricity and space, the magnetic fields that can be generated are not necessarily stronger than the permanent magnets.
3、What magnets are the hard disc head servo motors use?
The hard disc head servo motors are voice coli motors, which are the same as general permanent magnet synchronous motors; the magnetic material is rare earth permanent magnets NdFeB.
The servo driver controls the U/V/W three-phase electricity forming an electromagnetic field, and the rotor rotates under the action of this magnetic field. At the same time, motor built-in encoder feedback signal to the driver, the driver will compare the target value according to the feedback value, so as to adjust the angle of the rotor rotation. The precision of servo motor depends on the precision of encoder (line number).
PS: When the servo motor is working, it should avoid the entering of oil and water. Because the servo motor is not the fully waterproof equipment, it is not suitable to put it in the water or oil environment. While connecting to the reduction gear, users should pay attention to prevent the oil of reduction gear from entering the motor, as well as preventing cables from oil and water.
