R911284531
The R911284531 (MHD115B-058-NP0-BN) is a Bosch Rexroth Indramat MHD series synchronous motor, weighing 40 kilograms with dimensions such as 180 millimeters for the centering diameter, 431 millimeters for motor length, and 192 millimeters for the flange size. Environmentally, it can operate between 0 to 40 degrees Celsius and be stored between -20 to 80 degrees Celsius from 0 to 1000 meters altitude. It needs to be stored horizontally in a dust-free, vibration-free area with the plastic protective sleeve on the drive shaft, guarding it from moisture and mechanical damage. It also needs to be transported horizontally and protected from impacts.
Prior to mounting, the shaft's plastic protective sleeve can be removed. The highlight features of the R911284531 (MHD115B-058-NP0-BN) include digital servo feedback, and a shaft with a keyway and sealing ring designed to avert oil leakages and dust or moisture infiltration, securing an IP65 protection rating on the motor housing. The optional holding brake is allowed to be ordered separately if needed. With a liquid cooling and natural convection design, it has 1200 Watts nominal power loss, 10 to 40 degrees Celsius for coolant inlet temperature, 3 bar system pressure, and 0.11 liters for cooling duct volume. At standstill with liquid cooling, it sustains a continuous motor torque of 95 Nm and a continuous current of 118.2 Amps.
