The R911251938 (1MS160F-4U-A1) is a stator unit for Rexroth IndraDrive systems, intended for integration with the 1MB frameless spindle motor, frame size 160 and motor length F. This component is part of the 1MS series and utilizes an aluminum stator cooling jacket for liquid cooling, promoting efficient thermal transfer to the coolant within the spindle housing. An air gap is present to facilitate heat dissipation from the rotor. The stator is equipped with a 1.5 m electrical loom comprising three power wires within a high-temperature resistant protective hose. It is classified with an IP00 rating, necessitating additional protective measures in operational environments. Windings are identified by codes 4A, 4B, and 4D.
