1MS140B-4B-A1/S010

The Bosch Rexroth Indramat 1MS140B-4B-A1/S010 motor from the 1MB High-Speed Asynchronous Motors series combines a compact design with robust winding options, featuring a Motor Length B, Motor Size 140, and dual Windings Code 4A, 4B for flexible performance. Engineered for high dynamics, its stator assembly accepts a standard 1.5 m cable connection and is enclosed in an aluminum jacket that ensures structural integrity. A liquid cooling system maintains optimal thermal conditions under continuous operation, while the streamlined housing minimizes footprint in tight installations. This motor model is specified for demanding industrial tasks, providing reliable output across a wide speed range.

Featuring a rated power 3.7 kW at a rated current 25 A, the 1MS140B-4B-A1/S010 delivers a rated torque 7 Nm at rated speed 5 000 rpm while sustaining a heat dissipation 1 kW load with a coolant flow rate of 1.4 l/min. Its net weight of 5.3 kg and compact dimensions support high power density, and the maximum speed of 20 000 rpm accommodates precision applications. Under transient loads, the stator’s thermal time constant of 5 min protects internal components from thermal stress. Peak performance is highlighted by a maximum torque of 17.5 Nm and a peak current of 52.7 A, ensuring rapid acceleration and deceleration cycles.

Integration into automation environments is straightforward thanks to its open IP00 protection category and embedded NTC/PTC resistors for external controller feedback. The machine-ready motor exhibits exceptional reliability under extreme conditions, with a torque constant 0.34 Nm/A and 2 pole pairs guaranteeing smooth torque delivery. Ideal for high-speed spindles, rotary indexing tables, and dynamic machining centers, the 1MS140B-4B-A1/S010 enhances system performance while simplifying maintenance and control integration.
