HG-KR43G71-45

The Mitsubishi HG-KR43G71-45 is a low inertia, small capacity servo motor, specifically designed for applications that demand precise control and responsiveness. The motor produces a rated output of 0.4 kW, operating at a rated speed of 3000 revolutions per minute (rpm) while capable of reaching a maximum speed of 6000 rpm, and can instantaneously hit 6900 rpm when conditions require rapid movement.

This model does not include an electromagnetic brake or an oil seal. It features a high precision gear reducer type that utilizes a flange-mounting shaft output, which facilitates smooth operation and precise control. The standard straight shaft configuration enhances compatibility with various attachments and machines.

In terms of torque performance, the HG-KR43G71-45 achieves a continuous torque of 1.3 Nm, with the capability to provide a maximum torque of 4.5 Nm. The motor's rated current is specified at 2.6 Amps, while the maximum current can go up to 9.1 Amps, ensuring reliable performance under varying load conditions. Additionally, the inertia moment is calculated at 0.371 x 10⁻⁴ kg·m², and the motor is designed to handle a recommended load to motor inertia ratio of 25:1 or less, making it suitable for a wide range of operational demands.

The motor employs a 22-bit encoder, which is compatible with both absolute and incremental systems, providing a resolution of 4194304 pulses per revolution. This high-resolution feedback enhances position accuracy and control. Furthermore, the permissible shaft loads consist of a radial load capacity of 245 N and a thrust load of 98 N, allowing for substantial utility in diverse mechanical settings.
