Product Description:

Engineered by Pacific Scientific, the K43HRHL-LDK-NS-00 hybrid step motor has a NEMA 42 frame. This motor generates more torque than step motors that are produced by the manufacturer without Sigmax technology. The product is more cost-effective than a servomotor. This device can be used under adverse environmental conditions because of its rugged frame combined with a splashproof construction. The unit needs less input power than a three-phase motor with the same torque. It is characterized by a double-shaft configuration. This motor comes with its output shaft with the insertion of a straight key.

The motor has a 4.325-inch frame that is square in shape. This device has four leads for a series connection. The unit has three rotor stacks. It is used in applications like robotics and automation where accurate motion control is important. This motor is listed under the Powerpac sub-classification. It has a linear torque increase when the applied current is more than the rated current. This device has no demagnetization resulting in fast load movement. The unit comprises inserts made of rare earth materials in its stator. It depicts optimized torque production.

This motor is the right choice for direct drive applications for rotary motion when a direct coupling is used. The product supports critical position control and rapid bidirectional acceleration/deceleration. This device has fixed outer bearing races and has a very low thermal resistance of 1 degrees C/W. Its small signal impedance is measured using an impedance bridge at a frequency of 1 kHz. This hybrid step motor portrays good current utilization. The product can move loads at a fast rate. This device depicts a completely sealed housing. The unit portrays 41.3 rad/s^2 x 10^-3 torque-to-inertia ratio and 16.52 Nm holding torque. Its flux-focusing action helps in optimizing the flux paths.
