Product Description

The Bosch Rexroth MHD115A-058-NG0-BA is a servo motor. Its main components are a stator with winding, shaft, bearings, motor encoder, flange socket, and rotor. The main shaft on the motor is plain and is fitted with a sealing ring. The motor does not include an optional holding brake. MHD motors are made with special magnets that allow motor construction with low inertia. The location of the power socket is specified at the time of ordering. On the MHD115A-058-NG0-BA motor the power socket is on side B. MHD motors support multiple cooling options including natural convection, surface cooling and liquid cooling. The MHD115A-058-NG0-BA is designed for natural convection or surface cooling. Surface cooling is also known as forced air cooling and requires increased air flow for heat dissipation. The increased air flow is provided by a cooling fan.

Motor performance characteristics depend on cooling method and operating conditions. With surface cooling, the rated speed is 3000 RPM, the rated torque is 27.8 Nm, the rated current is 22.5 Amps and rated power output is 10.6 kilowatts. With natural convection at 100K overtemperature, the rated speed is 3000 RPM, the rated torque is 12.2 Nm, the rated current is 10.0 Amps and rated power output is 4.6 kilowatts. With natural convection at 60K overtemperature, the rated speed is 2000 RPM, the rated torque is 7.1 Nm, the rated current is 5.7 Amps and rated power output is 1.8 kilowatts. The MHD115A-058-NG0-BA includes integrated support for digital servo feedback. The motor flange size is 192 millimeters and the centering diameter is 180 millimeters. Shipping weight of the IP65 rated motor housing is 30 kilograms. The motor housing is painted matte black.
