1MS310B-6B-A1/S012

The Bosch Rexroth Indramat 1MS310B-6B-A1/S012 is part of the 1MB High-Speed Asynchronous Motors series, featuring a Motor Length: B, a Motor Size: 310, and a Windings Code: 6B, 6D, 6E. Designed as a stator assembly for high-dynamics spindle applications, it delivers smooth, continuous operation in machining centers, transfer lines, and grinding machines. This unit draws three-phase AC power and operates optimally within a temperature range of 0 to +40 °C at elevations up to 1000 meters above sea level.

In operation, the 1MS310B-6B-A1/S012 stator produces a continuous torque of 260 Nm at a rated speed of 700 rpm while drawing a current of 75 A. Under liquid cooling mode, it achieves a rated output of 19 kW, with water coolant supplied at 5 l/min to dissipate 3.5 kW of heat. The winding inductivity is 1.753 mH and the winding resistance is 0.173 Ω, ensuring precise electromagnetic performance and stable thermal behavior under continuous load conditions.

The stator is equipped with NTC and PTC resistors for seamless integration with third-party controllers and features built-in protection against overvoltage and over-temperature. It can reach a maximum speed of 2800 rpm, drawing a peak current of 164 A and generating a peak torque of 651 Nm. With 3 pole pairs and a total mass of 67 kg, the 1MS310B-6B-A1/S012 offers robust durability and high efficiency. Certified for demanding industrial environments, it enhances productivity and reliability in high-speed automation applications.
