Product Description:

The MHD115B-024-NP0-LA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. With a frame size of 115 and a B length code, the unit fits applications that need high torque in a compact housing. Winding code 024 identifies the electrical characteristics used with compatible MHD drive modules. A keyed shaft transmits torque directly to the driven load, and the power connector is arranged on the left side for straightforward cable routing. The motor is suited to positioning axes that require repeatable motion and stable output during automated operation.

A centering pilot of 180 mm aligns the housing on the machine face, while the square flange spans 192 mm to match common mounting patterns. Its electromagnetic circuit sustains 50.0 Nm of continuous stall torque, allowing tables, spindles, or presses to remain at zero speed without thermal overload. The housing is rated IP65, and the windings use Class F insulation for reliable operation at elevated temperatures. An axial shaft seal helps limit lubricant migration and blocks contaminants from reaching internal components. The motor is supplied without a holding brake, so power-off holding force must be provided by external means.

Motion accuracy is supported by the integrated Digital servo feedback (HSF) encoder, which provides incremental counts with a system precision of ± 0.5 angular minutes. Heat is removed through Natural convection, allowing continuous operation in ambient temperatures from 0 to 40 °C. The motor can be stored from -20 to +80 °C and installed up to 1000 m above mean sea level without derating. Optical feedback gives the drive controller continuous rotor position information for closed-loop speed and position control.
