Product Description:

The MHP112B-058-HP0-ANNNNN is a synchronous motor from Bosch Rexroth Indramat that belongs to the MHP Synchronous Motors series. Designed to convert commanded electrical power into accurate rotary motion, the unit operates as the mechanical actuator in position-controlled axes found in packaging lines, material-handling stations, and machining centers. When paired with a compatible servo drive, it supports repeatable motion for transfer, indexing, and feed applications that depend on controlled speed and position response.

With a continuous standstill torque window of 28.0 to 31.0 Nm, the motor can hold load inertia steadily when stopped while remaining within thermal limits. Its housing carries an IP65 protection category, so internal windings are shielded from dust ingress and low-pressure water jets that are common near wash-down workcells. Position data are returned to the drive through an incremental encoder with 2048 increments, giving the controller fine resolution for closed-loop velocity and position regulation. Mechanical coupling is made through a keyed shaft with a sealing ring, which transmits torque positively and helps protect the shaft exit area from contamination. Operation is specified over an ambient range of 0 to +40 °C, allowing installation in standard industrial spaces without additional climate conditioning.

The motor uses winding and thermal features suited to continuous servo operation. The stator is wound to code 058, which aligns coil resistance and inductance with compatible drives for efficient current use. Heat is removed by natural convection, eliminating the need for forced-air accessories. The insulation system is class F, permitting winding temperatures up to 155 °C during heavy duty cycles without premature varnish breakdown. The unit is delivered without a holding brake, so the axis must be secured at rest by drive torque or external mechanical means.
