Product Description:

The MHD115C-058-PG1-LA belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a permanent-magnet servo motor intended to deliver closed-loop position and speed control inside automated machine axes, pick-and-place gantries, and similar motion tasks. Its synchronous design supports accurate rotary motion where repeatable response is needed during positioning and speed regulation. The motor is suited for servo-driven equipment that must maintain stable motion under changing loads.

This model supplies 70.0 Nm of continuous standstill torque and includes a holding brake that can clamp the shaft at the same torque level when power is removed. A flange diameter of 192 mm mates to standard mechanical interfaces. The housing has a protection grade of IP65, so dust and water jets do not enter the enclosure. Cooling relies on natural convection, so no external fan or liquid circuit is required during nominal duty. The windings use insulation class F, which allows internal temperatures up to 155 °C. Power is routed through a left-side connector, and the plain shaft includes a shaft seal. This layout keeps cable routing to one side of the housing and helps in compact machine installations. The motor has frame length C, frame size 115, and winding code 058.

Digital servo feedback is provided by an encoder with absolute multi-turn feedback for more than 4096 revolutions, and the optical scanning method yields a system accuracy of ± 0.5 angular minutes. A centering pilot of 180 mm helps align the motor concentrically with the driven machine. Rated operation is allowed from 0 to 40 °C. Storage is tolerated from -20 °C to 80 °C, and installation is permitted up to 1000 m above sea level without derating. Multi-turn position retention allows the control system to track shaft location across repeated revolutions without losing reference after one turn.
