Product Description:

Bosch Rexroth Indramat manufactures the MHP071A-061-HG0-UNNNNN synchronous motor for its MHP Synchronous Motors series. The motor uses permanent-magnet excitation and is installed in packaging, material-handling, and general automation stations to convert drive-controller output into tightly regulated rotary motion across a moderate speed range. Its compact 71-frame housing fits into machine spaces, while the encoder channel feeds position data back to the control loop for closed-loop velocity and position regulation.

The housing carries a protection rating of IP65, so the internal windings, bearings, and encoder remain sealed against dust ingress and low-pressure water jets encountered during machine washdown. With natural convection cooling, the stator can deliver a continuous standstill torque of 3.5 Nm without external fans, and heat is removed through the surface area of the ribbed frame. The acceptable ambient range of 0 to +40 °C matches standard factory floor climates, and operation beyond that window requires derating. Position feedback is supplied by an incremental encoder with 2048 increments, giving 8192 counts per mechanical revolution after fourfold evaluation in the drive and enabling fine speed regulation at low rpm. The windings are insulated to Class F, permitting a maximum winding temperature of 155 °C during transient peaks, and the motor is supplied without a holding brake, so any static load must be secured by drive torque or an external mechanical catch.

Its mechanical interface uses a plain shaft with a sealing ring to guard the front bearing against coolant splash. Encoder and power leads exit through a turnable 270° connector that can be oriented after mounting to streamline cable runs. The electromagnetic setup follows winding code 061, which is optimized for medium-voltage drives. The compact frame identified as size 71 corresponds to stator length code A, which helps keep the motor short for installations with limited space.
