MITSUBISHI HA-LF20K1 Product information and technical parameters：
Brand: MITSUBISHI
Name: Low inertia medium capacity motor
Model: HA-LF20K1
Motor series: low inertia, medium capacity.
Rated output power: 20.0kw.
Rated speed: 1000rpm.
With the brake: without.
Shaft end: straight shaft.
The rotor of the servo motor is a permanent magnet, which is controlled by the U/V/W,
The rotor rotates under the action of the magnetic field, and the encoder feedback signal of the motor is given to the driver,
According to the feedback value and the target value, the driver adjusts the rotation angle of the rotor.
Accuracy of the servo motor depends on the accuracy of the encoder (number of lines).

Motor series: low inertia, medium capacity.
Using a serial absolute / incremental encoder.
Rated output power: 3.5kw.
Rated speed: 3000rpm.
With a brake band.
Shaft end: straight shaft.
Performance comparison of servo motor and stepping motor.
Stepper motor as an open-loop control system, and modern digital control technology has the essential link HA-LF20K1.
In the current domestic digital control system, stepping motor is widely used HA-LF20K1
With the emergence of digital AC servo system, AC servo motor is more and more used in digital control system.
In order to adapt to the development trend of digital control, most of the motion control system adopts stepping motor or full digital AC servo motor as executive motor HA-LF20K1.
Although they are similar in control mode (pulse train and directional signal), there are great differences in performance and application.
The use performance of the two are compared. Motor series: low inertia, medium capacity.
Rated output power: 15.0kw.
Rated speed: 2000rpm.
With the brake: without.
Shaft end: straight shaft.
Brushless motor has small size, light weight, large output, fast response, high speed, small inertia, smooth rotation, and stable torque HA-LF20K1.
Control is complex, easy to realize intelligent, and its electronic commutation method is flexible, can square wave commutation or sine wave commutation.
Motor maintenance free, high efficiency, low operating temperature, electromagnetic radiation is very small, long life, can be used for a variety of environments.
AC servo motor is brushless motor, which is divided into synchronous and asynchronous motor,
At present, the general use of synchronous motor control, which is a large range of power,
Can do a lot of power.
Large inertia, the maximum rotation speed is low, and with the increase of power and rapid reduction.
So it is suitable for the application of low speed and stable operation. Drive: MR-H_ACN series SSC-NET compatible AC servo.
Rated output: 22KW.
The servo controller can easily transfer the operation module and the field bus module through the automation interface,
At the same time using different fieldbus modules to achieve different control modes (RS485, RS232, optical fiber, InterBus, ProfiBus),
And the control mode of general inverter is single HA-LF20K1.
The servo controller is directly connected with a rotary transformer or an encoder, which forms a closed loop of speed and displacement control.
The general inverter can only form an open loop ccontrol system HA-LF20K1.
Servo controller of the control parameters (such as steady-state accuracy and dynamic performance) is better than the general inverter.
