3. competitive price,high quality 
Ac servo motor and brushless motor, divided into synchronous and asynchronous motor, the current motion control with synchronous motor, in the scope of its power generator price is big, can do a lot of power. www.facebook.com/guohong.trading Big moment of inertia, high rotational speed is low, and with the increasing power and fast. Thus suitable for the application of low speed running smoothly. The electric water pump inside of the servo motor rotor is a permanent magnets, three-phase electric drive 3 phase induction motor control of U/V/W form the electromagnetic field, under single phase motor the action of rotating rotor in this field, at the same time, motor with three phase induction motor encoder feedback signal to drive, drive according alternator generator to the feedback value compared with the target, adjust the Angle of the rotor rotation.

The precision of the servo motor is determined by the precision of the encoder (line number). Motor servo motor is also called the implementation, in the automatic control system, is used as actuators, converts the received electrical signal into angular displacement or velocity of motor shaft output. Divided into two www.dongfeng- motor.com major categories of dc and ac servo motor, its main characteristic is, when the signal voltage is zero no rotation, speed decreases with the increase of torque and uniform ac servo is better, because it is squirrel cage induction motor a sine wave control, torque ripple is small. Dc servo is trapezoidal wave. But dc servo is simpler and cheaper.
