Product Description:

The MHP112B-035-HP0-ANNNNN is a permanent-magnet synchronous motor manufactured by Bosch Rexroth Indramat for the MHP Synchronous Motors series. In servo axes that require accurate velocity and position control, it converts commanded current from a compatible drive into rotary motion and feedback signals. With its medium frame size, the unit fits packaging, printing, and material-handling machinery that benefit from high dynamic response and repeatability. It is suited to machines that need repeatable indexing and smooth speed regulation during frequent duty cycles.

It supplies a continuous standstill torque of 28.0 to 31.0 Nm when cooled only by ambient air, giving a useful reference for constant-load sizing. The allowable ambient range of 0 to +40 °C keeps this rating valid without derating. An enclosure rating of IP65 seals the stator against dust and water jets, so the motor can be used in most factory areas without an added protective housing. The motor windings use insulation class F, which permits winding temperatures up to 155 °C during intermittent overloads. Position data leave the incremental encoder with 2048 increments, enabling tight control loops when paired with digital servo drives.

The mechanical interface uses a keyed shaft with a sealing ring to transmit torque while limiting lubricant migration. Heat is removed by natural convection, so no blower or coolant circuit is added to the motor housing. Electrical power is routed through a keyed connector on side A, and the feedback connector is placed adjacent to it to keep cable routing compact. The motor uses size 112 stator laminations and length code B, which set the active magnetic volume for this housing. Winding code 035 sets the electrical resistance and inductance for moderate current demand. There is no integrated holding brake, so static holding must be provided externally when required.
