Product Details

  • HF Series AC Servo Motor (HFKP73)
  • Manufacturer: Mitsubishi
  • Series: HF Series

Product Description

The Mitsubishi HF-KP73 (HFKP73) is a 750W HF series servo motor. The torque of this servo motor is generally 2.4 (N x m) or 340 (oz x in), but it is allowed to be increased to, at most, of 7.2 (N x m) or 1020 (oz x in). Even though this is the case, when the torque is being augmented, it can reach a temporary torque of 8.36 (N x m) or 1180 (oz x in). Then, the servo motors current is 5.2A, yet the current is authorized to reach operate at 15.6A. The HF-KP73 servo motor has an appraised speed of 3000rpm, but it may extend to a speed of 6000rpm. It also may shortly obtain a speed of 6900rpm. And finally, the moment of inertia is 1.43 J(x10^-4kg x m^2) or 7.82 J(oz x in^2).

The HF-KP73 servo motor may hook to multiple servo amplifiers. The servo motor is able to link to one of four servo amplifiers, the MR-J3-70A, MR-J3-70B, MR-J3-70B-RJ006, and MR-J3-70T. There are a couple of means to attach the servo motor to the servo amplifier. The primary means is to link to the selected servo amplifier’s CN2 port. But, the HF-KP73 servo motor may also connect to the any of the available servo amplifier’s CNP3 connector which may also be called U, V, W terminal.

The HF-KP73 servo motor may is not only a low inertia motor, but also a small capacity motor. This type of servo motor may link via the spindle to a huge variety of devices.
