Product Description:
The MHD093C-058-NP0-BN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Designed for closed-loop control of rotary axes, the motor converts drive current into controlled torque so that conveyors, pick-and-place gantries, and forming spindles can follow programmed motion profiles. Its frame corresponds to motor size 093, and the internal stack length is coded as C, placing the motor in the middle of the family’s continuous power range for general industrial automation tasks. The product relies on external drive electronics for commutation and uses standard winding insulation for operation with compatible digital drive controllers, allowing it to support coordinated speed and position control in automated equipment.
The stator winding identified by 058 provides the electrical resistance and inductance needed for continuous operation at a standstill torque of 23.0 Nm, enabling stable holding force without overheating. Heat generated in the copper is removed through liquid cooling, which circulates coolant through channels in the housing and sustains rated output during high duty cycles. Mechanical alignment is simplified by a 130 mm centering diameter and a flange that spans 140 / 150 mm, giving a predictable fit against standard IEC gearboxes. These dimensions, combined with the C-length stack, balance inertia with thermal capacity for medium-inertia axes in multi-axis machines that cycle repeatedly through acceleration, positioning, and dwell periods.
The rotor carries a keyed shaft, and there is a shaft seal so lubricant or coolant from adjoining machinery cannot enter the winding cavity. Power is fed through an output connector on side B, easing cable routing where the motor back side must remain accessible and surrounding machine space is limited. Position data are generated by digital servo feedback (HSF); the sensor delivers relative multi-turn information to the drive and supports quick homing sequences during startup. Because the unit is supplied without a holding brake, external locking or drive-applied holding torque must be provided when power is removed.
