Product Description:
The MHD115B-058-NP0-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It supplies rotary motion for automated axes, allowing precise speed and position regulation in machining centers, pick-and-place gantries, and similar equipment. A keyed shaft and a factory-installed shaft seal support direct power transmission while helping keep lubricant inside the drive train. This shaft arrangement suits couplings and driven elements that require positive torque transfer during repeated starts, stops, and reversals. Because the motor is delivered without a holding brake, load position must be maintained by external mechanics or by the drive during power-off periods.
Under continuous stall conditions, the rotor delivers 50.0 Nm of torque, providing a stable reference for low-speed duty cycles and load-holding behavior under current control. The housing has an IP65 rating that helps block dust and water jets, and heat is removed through integrated liquid cooling passages to maintain winding temperature during sustained operation. Operation is permitted in ambient temperatures from 0 to 40 °C, while storage is allowed from -20 to +80 °C when the unit is de-energized. Accurate mechanical centering is provided by a 180 mm pilot diameter, and the power connector exits on side B so wiring can be routed away from the driven machine. This layout can simplify cable runs where the motor face is mounted close to machine structure or guarding.
The embedded encoder uses Digital servo feedback (HSF) and relative optical measurement to report rotor position to the drive, keeping measurement deviation within ± 0.5 angular minutes. This feedback arrangement supports commutation as well as closed-loop speed and position control without requiring a separate external sensor. Mounting is through a square flange that measures 192 mm across, matching the size 115 stator and motor length B. Electrical insulation meets class F, so the windings can safely reach 155 °C during brief overloads. Winding code 058 identifies the motor winding, and operation is permitted at elevations up to 1000 m above sea level.
