Product Description:

Bosch Rexroth Indramat manufactures the MHD115B-058-NG0-AN, a synchronous servo motor in the MHD Synchronous Motors series for demanding motion loops in packaging, metal-cutting, and material-handling cells. The motor occupies the 115 frame and the B length category, so it delivers high electromagnetic density without expanding the machine envelope. A 192 mm square flange simplifies rigid mounting to gearboxes or direct-drive loads, and its housing is prepared for coolant passages that let the unit exchange heat with external chillers. The motor converts commanded current into precise rotary motion for axes that require accurate torque and speed regulation during continuous machine operation.

Its electromagnetic section is rated for a continuous standstill torque of 50.0 Nm, allowing the shaft to resist static process loads without overheating. Heat generated in the stator is removed by an internal jacket that supports liquid cooling, so output capability remains stable during prolonged duty cycles. The housing carries an IP65 sealing grade that blocks dust ingress and water jets in open machine environments. Rotor position is sampled by Digital servo feedback (HSF), and this encoder works with winding code 058 to return high-resolution motion data to the drive. Mechanical centering against adjoining parts is established by a 180 mm pilot diameter, which helps align the motor accurately during installation.

The motor performs within an ambient range of 0 to 40 °C and may be stored between -20 °C and +80 °C without affecting materials or magnetization. Position control accuracy reaches ±0.5 angular minutes, and the drive evaluates the relative detection signals in real time during operation. A plain shaft with a shaft seal transmits torque, while class F insulation permits winding temperatures up to 155 °C. The motor is supplied without a holding brake, uses a power connector on side A, and can be installed up to 1000 m above mean sea level without derating. When the axis must remain fixed at standstill, holding force must be provided by the drive or by external machine hardware.
