Name: Medium inertia small capacity servo motor
Model: HG-SR121B
Servo motor series: medium inertia, small capacity.
Rated output: 1.2kw.
Rated speed: 1000r/min.
Electromagnetic brake: incidental.
Power supply: 200V.
Stable driving of medium capacity and medium inertia type products.
Through the optimization of structural design, to achieve the minimum length of the industry.
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.

1 axis servo amplifier.
MITSUBISHI general AC servo amplifier MELSERVO-J4 series.

Power specification: single phase AC200V.
Pulse train and analog input as universal interface.
Can choose the position, speed and torque control mode.
The use of advanced tuning features such as advanced vibration suppression control and adaptive filter,
Greatly improve the performance of the machine.
MR-J3, your partner.
Higher performance, more features, more convenient to use.
Highest performance in the industry.
Speed response frequency up to 2.1kHz. Servo motor series: low inertia, medium / high power.
Rated output: 2.0kw.
Rated speed: 3000r/min.
Electromagnetic brake: No.
Shaft end specification: Standard (straight axis).
Voltage: 400V level.
Features: low inertia for high speed / acceleration and deceleration operation occasions.
IP level: IP67.
Application example:
1, food processing machinery.
2, printing machine.
3, injection molding machine (11KW, 15KW).
4, large press machine (11KW, 15KW).
The protection level of the HF-SP/HF-JP series servo motor is IP67 (except the shaft part).
Low inertia of the power servo motor (0.5kW ~ 9kW), the maximum speed: 6000r/min (rated speed: 3000r/min),
Suitable for high frequency positioning and acceleration / deceleration operations, especially for food processing machines and printing machines.
Low inertia, high power, no cooling fan servo motor (11kW and 15kW), maximum speed: 3000r/min (rated speed: 1500r/min).
The motor structure is more compact due to the adoption of the non cooling fan design, and the connnection is reduced by using the power source connector HG-SR121B.
(compared with the HF-LP series servo motor with the same power, the volume is reduced by about 46%, and the weight is reduced by about 34%,
Suitable for high frequency positioning annd acceleration / deceleration operations, especially for injection molding machines and large presses HG-SR121B.
HF-JP703 (4) /903 (4) maximum speed: 5000r/min.
