Product Description:
The MHP090B-035-HP1-UNNNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MHP Synchronous Motors series. It is intended for positioning and velocity control duties in automated assembly lines, material handling axes, and packaging equipment. By converting commanded drive currents into precisely regulated mechanical motion, the unit forms the electromechanical link between an Indramat drive controller and the machine load, and it fits installations where medium frame size and sealed construction are required in demanding industrial surroundings.
At standstill with natural convection cooling, the motor can deliver a continuous torque of 12.0 Nm, providing sufficient holding force for mid-range payloads. Winding code 035 indicates the voltage constant and thermal loss profile expected by compatible drive modules. Frame size 090 sets the mounting pitch and shaft height, while the B active length extends the magnetic core for higher sustained output. Position feedback is produced by an incremental encoder with 2048 increments, allowing fine-resolution speed loops without absolute referencing. Thermal endurance is supported by insulation class F, which permits winding temperatures up to 155 °C during cyclic duty.
The motor carries a protection rating of IP65, so its housing resists dust ingress and water jets when mounted on open machinery. Operation is permitted between 0 to +40 °C, matching typical industrial ambient conditions around automated equipment. An internal holding brake produces 11.0 Nm of static torque to secure vertical axes during power removal, and the keyed shaft with a sealing ring transmits load while restricting lubricant escape. Power cables attach through a 270° rotatable connector, simplifying routing in tight enclosures, and cooling relies on natural convection without a separate fan. This layout also helps when cable entry angles are limited by nearby machine guards or frame members.
