Product Description:
Bosch Rexroth Indramat produces the MHD093B-035-PP1-BN as part of the MHD Synchronous Motors series. This product is a brushless AC servo motor that converts electrical input into controlled rotary motion for automated equipment such as packaging stations, material-handling gantries, and machining centers. Within an Indramat drive system, the motor supplies programmable torque, speed, and position so that machine axes follow command profiles precisely, enabling repeatable production cycles and high positional accuracy.
The motor's mechanical and thermal ratings affect how it is installed and loaded. It delivers a continuous standstill torque of 17.5 Nm, allowing axes to hold static loads without additional gearing. Heat generated by this torque is removed through a liquid cooling jacket that circulates coolant around the stator, permitting higher power density than air-cooled designs. The mounting interface uses a square flange of 140 / 150 mm with a concentric locating shoulder of 130 mm to keep the housing centered on the machine frame. Rotor position is reported by digital servo feedback that streams incremental and serial data to the drive for closed-loop control. Power enters the motor through an output connector on side B, keeping the cable run away from adjacent moving parts and simplifying cabinet routing.
The auxiliary features support holding, sealing, and position measurement. A spring-applied brake supplies 22.0 Nm of static torque so vertical or suspended loads stay in position when the drive is disabled. Torque is transferred through a keyed shaft, which provides positive mechanical engagement with couplings or pulleys, while a shaft seal helps prevent fluid ingress during washdown duty. For multi-turn applications, the integrated encoder provides absolute position tracking for more than 4096 revolutions, letting the controller read position immediately after power-up without homing. Motor length B, frame size 093, and winding code 035 suit the electromagnetic package to drives that must accelerate heavy loads in continuous-duty environments.
