Product Description:

The MHD093B-065-NP0-AA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Intended for closed-loop motion axes, the unit converts drive current into controllable rotary torque so that automated machinery can position loads with repeatable accuracy. It is supplied as a bare motor without a holding brake, so passive load holding must be provided by an external clamping device when required.

The motor can deliver a standstill torque of 17.5 Nm, providing adequate low-speed force for indexing tables, presses, or transfer stations. A centering diameter of 130 mm aligns the stator housing precisely against a machine reference face, while a 140 / 150 mm flange provides bolt patterns compatible with common gearboxes. With a protection rating of IP65, the housing is sealed against dust ingress and water jets so it can operate next to coolant lines or cutting fluid. Heat is removed through natural convection, meaning surface radiation and ambient airflow maintain winding temperature without auxiliary fans. The windings use insulation class F, and the enamel and slot liners tolerate internal hot-spot temperatures up to 155 °C before dielectric strength degrades.

Rotor position is monitored by digital servo feedback (HSF) that uses an optical measurement method and supplies relative counts for high-bandwidth control loops. System deviation remains within ± 0.5 angular minutes, which is suitable for precision pick-and-place or coordinated multi-axis paths. The motor should operate in ambient temperatures from 0 to 40 °C; outside this range, torque derating or condensation may occur. Storage is permissible down to −20 °C, and installation heights are limited to 1000 m above mean sea level to avoid reduced air density. A keyed shaft transmits torque mechanically, and a shaft seal blocks lubricant seepage along the journal to simplify coupling to gear reducers through standard hubs.
