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,
1, large starting torque.
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 0.5-100W small power control system.

HC-UF73
SS1 functions can be realized by using the MR-J3-D05 security logic unit.
MR-J3-BS uses a full closed loop control system.
Compatibility with MR-J3-B.
MR-J3-BS installation, wiring and connectors are the same as the MR-J3-B, so do not change the existing connection will be easy to MR-J3-B
Change to MR-J3-BS HC-UF73.
Security functions are connected to the CN8 interface through an external security circuit to increase the MR-J3-BS driver security.

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.
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.Type: HF-SE servo motor, medium inertia power.
Rated output power: 2.0kw.
Rated speed: 2000r/min.
Electromagnetic brake: No.
Oil seal: No.
Servo motor can make control speed, position accuracy is very accurate,
The voltage signal can be converted to torque and speed to drive the control object.
Servo motor rotor speed is controlled by the input signal, and can quickly response,
In an automatic control system, used as an actuator,
With electromechanical time constant, high linearity, initiating voltage characteristics,
The signal can be converted into a motor shaft on the angular displacement or angular velocity output.
Divided into DC and AC servo motor two major categories, the main features are,
When the signal voltage is zero, the rotation speed increases with the increase of torque.
Servo amplifier terminals are used to reduce the required wiring time.
The connector is located in front of the servo amplifier, which is convenient for cable connection.
The gain adjustment can be easily carried out by the real-time automatic tuning function.
