Product Description:

The MSS102B-0800-FA-N0CN-NNNN stator is produced by Bosch Rexroth Indramat for the MSS Synchronous IndraDyn H Motors series. As the fixed portion of a high-performance servo pair, it supplies the rotating magnetic field that drives a matched rotor and enables precise velocity or position control on automated production lines. The housing is prepared for liquid cooling so the assembly can transfer high mechanical power without transmitting excess heat to the machine frame. Because this unit is only the stationary motor section, it must be paired with a compatible rotor and installed in an appropriate motor housing before operation.

This model develops its continuous output at a rated speed of 8000 rpm while holding a rated torque of 10.7 Nm. Under these conditions, it converts electrical energy into a rated mechanical power of 8.96 kW and draws a rated current of 16.9 A from the drive. When commanded for brief accelerations, the motor can reach a maximum speed of 22500 rpm, which helps shorten cycle times in high-throughput stations. The electrical design includes three pole pairs to match IndraDrive inverter operation, and winding resistance together with iron losses accounts for 1.09 kW of heat that must be removed by the coolant circuit.

The short-path coolant duct holds 0.018 L of fluid and supports a flow of 3 L/min at an inlet pressure of 5 bar, with only 1.4 bar of pressure loss across the jacket. This cooling arrangement keeps copper temperature within acceptable limits even when the shaft delivers a peak torque of 36.7 Nm or the drive demands a peak phase current of 52 A. The stator has an IP00 rating, so it must be mounted inside a sealed motor housing before use. The laminated core and coil package weigh 5.8 kg, which supports fast speed changes while keeping the assembly suitable for compact gantry or spindle modules.
