Product Description:
The MHD115A-035-PG0-BA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for closed-loop position and velocity tasks in automated machinery, using an internal encoder to transmit absolute position data to the drive controller. The motor is built for installation on a 192 mm square flange and ties directly into drive axes that need precise rotary motion without mechanical backlash.
This model can deliver a continuous standstill torque of 32.0 Nm, so it is able to hold or slowly move substantial loads while remaining within thermal limits. Its housing is sealed to IP65, preventing dust ingress and water jets from affecting the windings or bearings. Heat is removed by natural convection, eliminating the need for forced-air fans and simplifying airflow requirements around the motor. The mounting interface corresponds to a 192 mm square flange, while an 180 mm centering diameter maintains concentric alignment with gearboxes or machine frames. Rotor position is monitored through digital servo feedback with an integrated optical sensor that supports absolute position reporting over more than 4,096 revolutions, improving homing accuracy and reducing repeat reference runs. Electrical power is routed to side B through an output connector, which streamlines cable runs inside tight enclosures.
The motor uses a Class F insulation system, allowing winding temperatures up to 155 °C during intermittent overloads. Rated operation is permitted in ambient air from 0 to 40 °C, and storage can occur between -20 °C and 80 °C without degrading magnet strength. A plain shaft transmits torque directly, and a shaft seal is fitted to limit lubricant loss and stop contaminants from reaching the bearings. Closed-loop precision is supported by a system accuracy of ± 0.5 angular minutes, minimizing positional error in indexing tables, pick-and-place heads, and similar servo-controlled axes. The motor is supplied without a holding brake and may be mounted up to 1,000 m above mean sea level when convection cooling is maintained.
