Product Description

The Bosch MHD115B-058-NP0-AN is a servo motor. It is part of the MHD series of synchronous motors. As per the type code, the motor frame size is 115 and the frame length is B. The main shaft on the motor includes a keyway and a sealing ring. Approximately 80 millimeters of the main shaft are outside the main motor housing. The diameter of the motor shaft is 38 millimeters. The length of the MHD115B-058-NP0-AN motor is 431 millimeters and its centering diameter is 180 millimeters. The motor is a flange mounted device and its flange size is 192 millimeters. The digital servo feedback feature enables a servo controller to accurately control motor parameters including speed and torque output. The keyway on the shaft ensures torque transfer by preventing relative rotation between the motor shaft and the machine.

Bosch provides optional holding brakes for MHD motors. However the MHD115B-058-NP0-AN is supplied without a holding brake. The motor gets power through a power cable from the servo controller. This power cable connects to a socket on side A of the motor housing. The housing of the MHD115B-058-NP0-AN is designed for liquid cooling and natural convection. Liquid cooling relies on the flow of coolant through a cooling jacket on the motor stator. Liquids have a higher density than air or other gases and are able to dissipate a higher amount of heat per unit time. That is why liquid cooling is used for applications that involve the highest of application loads. With liquid cooling the MHD115B-058-NP0-AN motor delivers 95 Nm continuous torque at standstill and 118.2 Amps continuous current at standstill. In contrast, with natural convection the motor delivers 50 Nm continuous torque at standstill and 62.2 Amps continuous current at standstill.
