Product Description:

The MHD093B-035-NG0-AA belongs to the MHD Synchronous Motors series from Bosch Rexroth Indramat. As an AC servo motor, it is installed on precision axes where closed-loop control, position repeatability, and moderate holding torque are required. The unit integrates into CNC and assembly lines through its digital feedback channel, supplying the drive controller with accurate rotor position data for coordinated motion.

This motor can deliver 17.5 Nm of continuous standstill torque, allowing it to hold or accelerate medium-inertia loads without thermal overload. Its aluminum housing is sealed to IP65, so dust ingress and water jets do not reach internal windings. Mechanical alignment is simplified by a 130 mm centering diameter that mates to machinery frames, while the square mounting pattern supports flanges sized 140 / 150 mm. Heat dissipates by natural convection, eliminating the need for external blowers. The windings use insulation class F for 155 °C thermal endurance, and power exits on side A through a single output connector. Position feedback is handled by a digital servo encoder (HSF); it measures rotor angle optically and reports relative counts to the drive. A shaft seal is fitted to protect internal bearings from oil splash.

Servo accuracy is ± 0.5 angular minutes, supporting interpolated moves that demand minimal following error. Continuous operation is allowed in ambient temperatures of 0 to 40 °C, and storage is acceptable from -20 to +80 °C without condensation. Installation at elevations up to 1000 m above MSL avoids derating, provided convection airflow remains unobstructed. The motor uses a plain shaft for zero-backlash coupling, and it is shipped without a holding brake, so external clamping devices must secure vertical axes when power is removed. Size code 093, length code B, and winding code 035 complete the ordering data and match compatible drive parameters.
