Product Description

The Bosch Rexroth MHD112B-048-NG1-BN is a synchronous motor. MHD motors, in combination with drive controllers, are designed for applications such as machine tools, packaging machines, food machines and automation. According to the motor type code, the motor frame size is 112 and the winding code is 048. The motor centering diameter is 130 millimeters and the shaft diameter is 32 millimeters. The MHD112B-048-NG1-BN is a flange-mounted motor. The size of the motor flange is 192 millimeters. The diameter of each hole on the motor flange is 14 millimeters. The overall length of the motor is 375 millimeters. The approximate motor mass is 34 kilograms. The MHD112B-048-NG1-BN is a designed for a maximum speed of 4500 RPM.  The rated speed is 2800 RPM for all operating conditions. The motor housing is IP65 rated and is designed for natural convection or surface cooling.

With natural convection, the continuous torque output of the MHD112B-048-NG1-BN is 28 Nm and the continuous current output is 35.6 Amps. With surface cooling, the continuous torque output of the MHD112B-048-NG1-BN is 42 Nm and the continuous current output is 53.4 Amps. The moment of inertia of the rotor on the motor is 0.0192 kg m². Bosch has provided a 22 Nm holding brake. The brake only releases the motor shaft and allows it to spin when a 24 Volts DC signal is applied. The permitted storage temperature is -20 to 8 degrees Celsius and the permitted working temperature is 0 to 40 degrees Celsius. The MHD112B-048-NG1-BN motor includes support for digital servo feedback. The power connection is on side B of the motor housing. The main motor shaft is plain and comes with a sealing ring.
