1MS376B-QA-A2/S041

The Bosch Rexroth Indramat 1MS376B-QA-A2/S041 is a high-performance member of the 1MB High-Speed Asynchronous Motors series, combining a motor size 376 frame with a motor length B and an inside diameter of rotor 41 mm in a single compact package. It features a compact design optimized for demanding industrial applications and is protected by a rust-resistant varnish that guards against corrosion in harsh environments. This stator assembly delivers consistent performance while occupying minimal space, making it ideal for installations where footprint and durability are critical. Engineered to maintain over 90 percent operational efficiency across extended duty cycles, it is a cost-effective solution for continuous use.

Reliability is further enhanced by an integrated liquid cooling mechanism that stabilizes temperature under heavy loads and an aluminum cooling jacket that accelerates heat dissipation. A factory-fitted 1.5-meter cable ensures simple connection to three-phase power supplies without additional cabling costs. The robust construction tolerates mechanical stresses, while a highly resistant insulation system and corrosion-proof varnish significantly reduce maintenance intervals. Designed for uninterrupted operation over years, the 1MS376B-QA-A2/S041 withstands industrial duty without sacrificing performance.

Electrical characteristics support precise control and predictable behavior: a torque constant of 8.49 Nm/A at 20 °C ensures direct translation from current to torque, while a nominal winding resistance of 0.742 Ω provides repeatable thermal performance. With a thermal time constant of 10 minutes, the motor stator reacts predictably to transient loads, simplifying thermal management in closed-loop drives. Routine cleaning to prevent dust accumulation preserves airflow and extends service life. Each unit ships globally with a one-year warranty, backed by Wake Industrial’s support network for rapid commissioning and reliable after-sales service.
