MHD115B-035
The MHD115B-035 belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It is an AC servo motor intended for closed-loop industrial axes where position, speed, and torque are regulated by a digital drive controller. By converting electrical power into controlled mechanical rotation, the unit supports tasks such as gantry movement, tool positioning, and conveyor indexing in automated lines. This operating principle allows the motor to respond quickly to command changes, maintain steady motion at commanded speed, and support repeatable axis behavior during start, stop, and positioning sequences. In automated equipment, that behavior helps the axis follow programmed acceleration and deceleration profiles while maintaining the commanded relationship between torque demand and shaft movement.
The motor uses a centering pilot of 180 mm, giving the mounting flange accurate concentric alignment with the driven machine frame. At zero speed, it can deliver a continuous shaft torque of 50.0 Nm, which provides static holding force without an external brake. A square flange measuring 192 mm on each side sets the bolt pattern for standard motor plates and gives the housing a consistent mounting outline. The frame code 115 identifies the stator diameter group, while winding code 035 indicates the electrical winding used for this motor and the current characteristics expected by the matched controller. Continuous torque at standstill is useful on axes that pause under load between motion steps, and the mounting dimensions help keep alignment stable during repeated operation.
Within the control system, the device is classified as a Servo Motor for encoder-based feedback operation with a digital controller. The length code B indicates an intermediate active stack that balances inertia and continuous output for medium-duty cycles. The unit remains part of the MHD Synchronous Motors family, so related motors in the same range can share a common mounting concept while using different windings or lengths. That layout allows the motor to fit applications that need a moderate installation envelope together with stable torque delivery and predictable response in repeated motion cycles. Its family relationship also keeps the platform consistent when similar axes require the same basic motor format but different performance levels.
