The Bosch Rexroth MHD series synchronous motor, R911284531 (MHD115B-058-NP0-BN), weighs 40kg with dimensions of 180mm centering diameter, 431mm motor length, and 192mm flange size. The motor functions optimally in temperatures of 0-40 degrees Celsius and can be stored within -20-80 degrees Celsius under 1000 meters altitude. The storage environment should be dust-free, vibration-free and horizontal. For protective measures, a plastic sleeve on the drive shaft prevents moisture and mechanical damage, only to be removed before installation. With features like digital servo feedback, a keyway shaft, and sealing ring for oil leakage and dust/ moisture infiltration prevention, the motor has an IP65 rated housing for dust and water protection . Separate orders are needed for holding brakes. Designed for liquid cooling and natural convection, the motor has a nominal power loss of 1200 Watts with a coolant inlet temperature ranging from 10-40 degrees Celsius, adjusting to a 3 bar minimum system pressure and 0.11 liters cooling duct volume. It offers a continuous torque of 95 Nm and current of 118.2 Amps at standstill.
