Product Details

  • HF Series Servo Motor LOW INERTIA 200W 3000RPM (HFKP23K)
  • Manufacturer: Mitsubishi
  • Series: HF Series

Product Description

The Mitsubishi HF-KP23K (HFKP23K) is a 200W Melservo HF series servo motor with a key. The servo motor with a key has a moment of inertia of 0.24 J(x10^-4kg x m^2) or 1.31 J(oz x in^2). The current is normally 1.4A, but nevertheless, it is able to be augmented to 4.2A, and maybe even temporarily 4.9A. The speed of the HF-KP23K servo motor with a key can function at the speed of 3000rpm, yet even 6000rpm may be achieved. It is even allowable to momentarily attain the speed of 6900rpm. The torque is usually operating at 0.64 (N x m), that is 90.6 (oz x in); however, the HF-KP23K servo motor with a key may have a torque as great as 1.9 (N x m) or 269 (oz x in).

There are four servo amplifiers, the MR-J3-20A, MR-J3-20B, MR-J3-20B-RJ006, and MR-J3-20T, that may be applied to the HF-KP23K servo motor with a key. There are two ways that the servo amplifiers concatenate with the servo motor with a key. The first way is by attaching the encoder of the servo motor with a key to the CN2 port of the selected servo amplifier. The HF-KP23K servo motor with a key may also connect to a power supply through attaching wire to the CNP3 (U, V, and W) connector.

The HF-KP23K servo motor with a key is a low inertia motor that may be linked to many different mechanisms applicable to a low inertia motor. Servo motors of the HF-KP series are also small capacity servo motors.
