HG-KR23G71-21

Mitsubishi's HG-KR23G71-21 is a low inertia and small capacity servo motor designed for performance in compact applications. This motor operates effectively with an output power of 0.2 kW and reaches a nominal speed of 3000 RPM. For users requiring burst performance, it can operate continuously at a maximum speed of 6000 RPM and temporarily reach up to 6900 RPM.

The motor architecture excludes both an electromagnetic brake and an oil seal, which may be relevant depending on the application. Incorporating a high-precision flange-mounted output shaft, this design is geared for accuracy and reliability. The standard straight shaft configuration simplifies integration with existing infrastructure.

In terms of torque capabilities, the continuous torque generated by the HG-KR23G71-21 is 0.64 Nm, while peak torque can soar to 2.2 Nm under certain conditions. This motor's performance metrics are further enhanced by its power dissipation, which is rated at 18.3 kW/s when operating at rated torque, indicating effective thermal management.

Current ratings for the motor are set at 1.3 A for nominal conditions; however, a maximum current of 4.6 A is permitted during demanding operations. Rotational inertia is noted at 0.221 × 10⁻⁴ kg·m², which plays a significant role in its responsiveness. Load specifications allow for a radial load capacity of 245 N and a thrust load of 98 N, making it adaptable for various light to moderate industrial applications.
