Product Description:

The MHD093B-035-NG0-BA synchronous servo motor is produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In numerically controlled production lines, it supplies regulated torque and speed so axes can follow drive commands with minimal lag during positioning, contouring, and feed motions. The motor couples directly to machine elements through its plain shaft, which suits installations that use external couplings, pulleys, or belt-driven mechanisms. It has no internal holding brake, so the rotor assembly stays lighter for frequent start-stop operation. A positive shaft seal helps keep contaminants away from internal components and supports use in general industrial environments.

The continuous torque available at standstill is 17.5 Nm, which supports static load holding and stable low-speed operation when the drive is properly matched to the application. The cast housing has a protection rating of IP65, which blocks dust ingress and resists low-pressure water jets in industrial areas. Spigot alignment uses a 130 mm centering diameter, and the flange bolt pattern follows a 140 / 150 mm square pitch for direct mounting to compatible machine interfaces. Heat is removed by natural convection, so the motor does not require an external blower. This cooling method keeps installation simple where free air circulation is available around the housing.

Rotor position is resolved by a digital servo feedback (HSF) encoder that uses optical scanning to generate high-resolution relative data for the drive controller. The feedback system supports a deviation of no more than ± 0.5 angular minutes, which helps maintain accurate interpolation in coordinated multi-axis motion. Safe continuous duty is specified for ambient conditions of 0 to 40 °C, and the windings use Class F insulation to handle normal thermal rise during operation. Storage is permitted from −20 to +80 °C, installation is allowed up to 1000 m above mean sea level, and the power connector is oriented toward side B to improve cable clearance at the rear of the motor.
