Product Description:

The MSS162J-0200-FR-N0CN-NNNN is a three-phase synchronous motor built by Bosch Rexroth Indramat for the MSS Synchronous IndraDyn H Motors series. In high-power automation cells, the unit converts electrical energy into regulated rotary motion under IndraDrive control. Its water-cooled housing permits sustained torque production while occupying less floor space than comparable air-cooled machines. This design makes the motor suitable for gantry axes, large press drives, and other installations that demand consistent speed accuracy under heavy mechanical loads.

During continuous operation, the motor delivers 120 Nm, so gear stages may be unnecessary in many load cases. This torque output is supported by a rated speed of 2,000 rpm, which corresponds to the synchronous frequency supplied by the drive. At the rated speed, the shaft delivers 25.1 kW while water circulates through a jacket that measures 180 mm in diameter and extends 381 mm along the stator. The cooling system requires a minimum coolant flow of 4 L/min to remove heat from the housing. At standstill, the windings can accept 45.7 A without excessive heating. The winding resistance is 0.46 ohms, which helps limit electrical losses during operation. The assembly weighs 46.1 kg, so it should be secured to a rigid mounting surface that can support its mass and operating forces.

For short operating intervals, the electromagnetic system can generate up to 275 Nm when the drive supplies a peak phase current of 128 A. Dynamic response is aided by a longitudinal inductance of 2.52 mH, allowing rapid magnetic flux changes while maintaining smooth current regulation. The motor has a thermal time constant of 5.1 min, indicating how quickly its internal temperature responds to changes in load. The enclosure has an IP00 protection rating and does not prevent contact with internal components or the entry of contaminants. The motor must therefore be installed within a suitable machine enclosure that blocks coolant spray and debris while providing adequate clearance for the 180 mm water-jacket connections.
