Product Description:
The MHD093B-035-NP0-RA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop positioning and velocity control in industrial automation, the motor works with digital drives to move machine axes, gantries, or transfer stations with repeatable accuracy. As a synchronous permanent-magnet unit, it generates torque in direct proportion to stator current, allowing precise response to command signals in assembly lines, packaging equipment, and material-handling systems. This operating style is well suited to indexing, transfer, and synchronization tasks where the commanded position must be reached quickly and then held with stable servo control.
At standstill, the rotor can deliver 17.5 Nm of continuous torque, so holding force is available during static pressing or vertical-load service without excessive heating. A centering pilot of 130 mm aligns the flange on gearboxes or mounting plates, helping reduce radial runout during installation. The motor housing carries an IP65 protection rating, which keeps out dust and low-pressure water in washdown areas. Rated operation is approved between 0 to 40 °C, which suits typical industrial environments. Heat is removed by natural convection, so no external blower or liquid circuit is required. Clearance around the housing should remain open so heat can dissipate from the ribbed surface.
For storage and transport, the windings tolerate temperatures from -20 to +80 °C when moisture is controlled. A keyed shaft transmits torque to couplings and pulleys, and a shaft seal helps keep coolant or lubricant out of the bearing chamber. The stator uses winding code 035, which matches the motor's electrical characteristics to compatible Indramat inverters. Position feedback is provided by an optical encoder with ±0.5 angular minutes system accuracy, and because the feedback is relative, the axis requires homing after power-up. Insulation class F supports elevated winding temperatures, and the power connector exits to the right for orderly cable routing.
