Product Description:

The MHD093A-035-NP0-LA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Sized 093 with length code A, it is intended for closed-loop motion axes that demand consistent torque and repeatable positioning. Relative position information is captured optically and fed back to the drive, allowing coordinated interpolation with neighboring axes. By combining electronic commutation with a rigid rotor construction, the unit suits gantry drives, tool spindles, and pick-and-place modules in general industrial automation. This arrangement helps the drive maintain stable motion during acceleration, deceleration, and synchronized axis movement.

With winding code 035, the motor supplies a continuous standstill torque of 12.0 Nm, enabling constant force without exceeding thermal limits. Heat is removed by natural convection, so no external blower or coolant circuit is required as long as ambient air remains within 0 to 40 °C. The housing carries a protection rating of IP65, which prevents dust ingress and tolerates low-pressure water spray. Rotor position is tracked by digital servo feedback (HSF) for real-time exchange with compatible drives. Mounting is through a square flange measuring 140 / 150 mm with a 130 mm centering pilot to keep the stator aligned with attached gearboxes or machine interfaces.

Electrically, its windings are insulated to class F, allowing conductor temperatures up to 155 °C during heavy cycles. The output shaft is a keyed shaft with a shaft seal that helps protect the internal bearings from splash and contaminants. Position repeatability is maintained within ± 0.5 angular minutes, supporting fine contouring and accurate return to commanded locations. The unit is supplied without a holding brake, so static locking must be provided externally when required. Power enters through a molded power connector that exits to the left side of the housing, which can simplify cable routing on multi-axis frames. Storage is permissible between -20 to +80 °C, and operation remains specified up to 1000 m above mean sea level.
