Product Description

The MHD115B-058-NP0-BN is a MHD series synchronous motor from Bosch Rexroth. Mechanical specifications for the motor include 40 kilograms weight, 180 millimeters centering diameters, 431 millimeters motor length and 192 millimeters flange size. Environmental specifications for the motor include 0 to 40 degrees Celsius working temperature, -20 to 80 degrees Celsius storage temperature and 0 to 1000 meters altitude. During storage the motor should be kept in the horizontal orientation. The location used for motor storage should be free of dust and vibrations. The plastic protective sleeve on the drive shaft should be kept in place during storage. The sleeve protects the main shaft from moisture and mechanical damage. The motor should be transported only in the horizontal position. The drive should be protected from impacts during transportation.

The plastic protective sleeve on the shaft of the MHD115B-058-NP0-BN should only be removed shortly before motor mounting. Features available on the MHD115B-058-NP0-BN include digital servo feedback, and a shaft with keyway. The shaft also includes a sealing ring. The purpose of the shaft seal is to prevent leakage of oil and protect the shaft from dust and moisture. Protection rating of the motor housing is IP65. This means that the motor is safe from dust and from low-pressure water jets. An optional holding brake, if required, has to be ordered separately. The motor is designed for liquid cooling and natural convection. Technical data for liquid coolant includes 1200 Watts nominal power loss, 10 to 40 degrees Celsius coolant inlet temperature, 3 bar minimum system pressure and 0.11 liters cooling duct volume. The continuous motor torque at standstill with liquid cooling is 95 Nm and the continuous current is 118.2 Amps.
