Product Description:
The MHD115A-058-PG0-BN servo motor is produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is intended for closed-loop industrial axes where precise torque generation and repeatable positioning are required. In automated equipment, the motor converts electrical energy from the drive into mechanical rotation for gear stages, linear actuators, and other driven loads.
At standstill, the motor can deliver a continuous torque of 32.0 Nm, which supports holding duty and low-speed indexing tasks. Heat produced during operation is removed by liquid cooling, allowing the motor to maintain output without excessive temperature rise. The housing is rated to IP65, which helps keep out dust and directed water jets during normal industrial use. A centering diameter of 180 mm supports accurate alignment on the machine interface. The windings use insulation class F, which allows elevated internal operating temperatures. The motor uses frame size 115 with length code A, and winding code 058 indicates the electrical characteristics expected by compatible drive modules. Electrical power is supplied to the stator through a rear-mounted output connector.
Position feedback is provided by an integrated digital servo encoder with absolute detection over more than 4,096 revolutions, and the system accuracy is rated at ± 0.5 angular minutes. The mounting flange measures 192 mm across, giving the motor a defined mechanical interface for installation. Continuous operation is permitted in ambient air from 0 to 40 °C, while storage is allowed from -20 to +80 °C. The motor can be operated at elevations up to 1000 m above mean sea level without derating. A plain shaft with a shaft seal transmits torque to the load, and the motor is supplied without a holding brake, so vertical axes require an external holding device. Power enters from side B through the output connector, which can help simplify cable routing along the machine frame.
