1MS376A-QB-A2/S010

The Bosch Rexroth Indramat 1MS376A-QB-A2/S010 from the 1MB High-Speed Asynchronous Motors series is a high-performance frameless stator designed for demanding spindle motor applications. Featuring a Motor Length of A, a Motor Size of 376, and a Windings Code with an Aluminum Cooling Jacket, this stator rapidly converts AC power to magnetic torque for precise, high-speed operation. Its primary role is to energize and control the rotor in a complete 1MB asynchronous kit, delivering the high dynamics and stability required in modern CNC and automation systems.

In terms of technical specifications, the 1MS376A-QB-A2/S010 stator is built with an integrated aluminum cooling jacket that efficiently dissipates heat during continuous duty cycles. The slender, compact Motor Length A profile allows for seamless integration into existing drive systems, while the large Motor Size 376 ensures robust magnetic flux generation. The aluminum jacket not only enhances thermal management but also contributes to reduced weight and inertia, enabling rapid acceleration and deceleration. The stator design complies with the stringent mechanical and electrical tolerances specified by Bosch Rexroth Indramat, ensuring consistent performance across a wide range of operating speeds and loads.

Beyond raw performance, the 1MS376A-QB-A2/S010 offers compatibility and durability suited to industrial environments. Equipped with built-in NTC and PTC temperature sensors, it supports integration with both Bosch Rexroth and third-party drive controllers for flexible system design. The stator carries an IP00 protection rating and must be installed in a secured enclosure under prescribed environmental conditions. It also utilizes a liquid coolant circuit to maintain optimal winding temperatures between 0 and +40 °C without power derating. Supplied with a detailed user manual, this stator provides reliable, maintenance-friendly operation, making it an ideal choice for high-speed, high-precision industrial spindles.
