MITSUBISHI HC-RF503B Product information and technical parameters:
Brand: MITSUBISHI
Name: Low inertia medium capacity motor
Model: HC-RF503B
Motor series: low inertia, medium capacity.
Using a serial absolute / incremental encoder.
Rated output power: 5.0kw.
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.
In the current domestic digital control system, stepping motor is widely used.
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.
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.

Servo motor series: ultra low inertia, low power.
Rated output: 0.4kw.
Rated speed: 3000r/min.
Electromagnetic brake: No.
Shaft end specification: Standard (straight axis).
Features: ultra low inertia is very suitable for high frequency operation.
IP level: IP65.
Application example:
1, insert machine HC-RF503B.
2, assembly machinery.
Rotary servo motor.
Numerous motor series and wide motor power range can be used to meet different applications HC-RF503B
The protection level of the HF-KP/HF-MP/HC-LP/HC-RP/HC-UP servo motor to improve the environmental safety is IP65 (except the shaft part). Servo motor series: medium inertia, small capacity.
Rated output: 3.5kw.
Rated speed: 2000r/min.
Electromagnetic brake: No HC-RF503B.
Oil seal: incidental (Note 1, note 2, note 3).
Power supply: 200V.
Note 1 through HG-KR and HG-MR series 0.1kW and HG-SR series can be supported.
Note 2 with the speed reducer case, do not configure the oil seal.
Note 3 with oil seal HG-KR, HG-MR series servo motor''s appearance size standard is different.
Stable driving of medium capacity and medium inertia type products.
Through the optimization of structural design, to achieve the minimum length of the industry HC-RF503B.
High speed & high torque. Shorten the positioning time, achieve high-speed equipment.
Reducing the electric torque ripple.
Through the combination of the optimal number of the motor and the slot number, the torque ripple is greatly reduced,
To further realize the smooth constant speed device.
Improve the environmental performance of HG-SR, HG-JR series of products using IP67. Drive: MR-H_ACN series CC-LINK features.
Rated output: 1.0KW.
The test system is composed of two parts, namely, the servo driver, the motor system and the host computer.
The host computer sends the speed command signal to the servo driver,
Servo drives start to run in accordance with the instructions.
In the course of operation, the running data of the servo system is collected by the host computer and the data acquisition circuit,
And carries on the preservation, the analysis and the display to the data. Because the motor is not loaded in this test system,
So compared with the previous two kinds of testing systems, the system has a relatively small vvolume,
And the measurement and control circuit of the system is relatively simple,
But it also makes the system can not simulate the actual operation of the servo drive HC-RF503B.
Usually, such testing system is only used to test the rotational speeed and angular displacement of the tested system under no-load condition,
And can not carry on the comprehensive and accurate test to the servo drive HC-RF503B.
