Product Description:

The MHP090B-035-HP0-UNNNNN is a three-phase synchronous servo motor from Bosch Rexroth Indramat and belongs to the MHP Synchronous Motors series. It is built to deliver precise torque and speed control when paired with intelligent drives, allowing tightly coordinated motion axes in packaging, printing, and material-handling lines. Its synchronous design supports repeatable response during starts, stops, and speed changes on automated axes. The motor has size code 090 and length code B, giving it a mid-range housing length for this frame.

At standstill, the motor supplies a continuous torque of 12.0 Nm when cooled only by ambient air. This value is supported by a natural convection housing that lets heat move away without auxiliary fans or liquid circuits. A keyed shaft with an integrated sealing ring transmits torque while helping block oil ingress. Because the unit is delivered without a holding brake, static loads must be secured through external mechanics or drive torque. The enclosure has an IP65 rating, so dust and water jets do not interfere with internal parts. Rotor position is monitored by an incremental feedback system that outputs 2048 increments per revolution, enabling tight position loops. This feedback signal helps the drive maintain accurate rotor alignment during low-speed motion and positioning tasks.

The motor can operate in ambient air from 0 to +40 °C without derating, so it can run in standard industrial environments without climate conditioning. Windings use Class F insulation, allowing internal temperatures up to 155 °C before aging accelerates. The insulation system supports thermal durability during continuous industrial duty. Power enters through a 270° turnable connector that can be rotated to suit cable routing in confined spaces. The electromagnetic parameters are indicated by winding code 035, and drive controllers use this code to apply matching current limits and commutation tables.
