Motor series: low inertia, medium and small capacity.
Using a serial absolute / incremental encoder.
Rated output power: 0.2kw.

Comparison of single phase induction motor and servo motor.
The working principle of the AC servo motor is similar to that of the single phase induction motor,
But the rotor resistance of the former is much larger than that of the latter,
So the servo motor is compared with the single machine asynchronous motor,
There are three notable features:
1, large starting torque HA-SH203 HA-SH203.
2, a wide range of operation.
3, no rotation phenomenon.
AC servo motor running smoothly, low noise.
But the control characteristic is non-linear, and because the rotor resistance is big, the loss is big, the efficiency is low,
Therefore, compared with the same capacity DC servo motor, the volume is large and the weight is heavy,
So it is only suitable for 0 HA-SH203.5-100W small power control system. Motor series: medium inertia, medium capacity.
Using a serial absolute / incremental encoder MITSUBISHI HA-SH203.
Rated output power: 5.0kw.
Rated speed: 2000rpm.
With the brake: without.
Shaft end: straight shaft.
The rotor of AC servo motor is usually made of squirrel cage, but in order to make the servo motor has a wide range of speed regulation, linear mechanical properties,
Without the "rotation" phenomenon and the performance of the fast response, it is compared with the ordinary motor,
The two characteristics of rotor resistance and moment of inertia should be provided MITSUBISHI HA-SH203.
At present, there are two kinds of rotor structure, one is the squirrel cage rotor, which is made of conductive material with high resistivity,
In order to reduce the moment of inertia of the rotor, the rotor is slender MITSUBISHI HA-SH203.
Motor: HA-SH type.
Power: 2.0kw.
Speed: 3000r/min.
The speed regulating motor can be divided into a constant speed motor, a stepless constant speed motor, a stepless speed changing motor and a stepless speed changing motor,
Can also be divided into electromagnetic induction motor, DC motor, PWM variable frequency motor and switched reluctancee motor HA-SH203.
The rotor speed of the induction motor is always slightly lower than that of the rotating magnetic field.
The rotor speed of the synchronous motor is not independent of the load size, but is always maintained as a synchronous speed.
