1MS105N-4A-A1

The 1MS105N-4A-A1, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors stator combines high-precision engineering with robust construction to form the core of frameless motor assemblies. Featuring a Frame Size: 105 and a Frame Length: N, it houses a 4A winding rated for a Nominal Current: 29 A and peaks at Max Current: 73.68 A to drive demanding applications. Integrated within its design is an Aluminum Cooling Jacket that uses Liquid Cooling channels for efficient thermal regulation. The stator’s purpose-built geometry ensures uniform magnetic flux distribution to propel the rotor with minimal losses.

Designed for seamless integration, the stator offers a Cable Exit Location: Stator end and a Cable Length: 1.5 m axial connection with a reinforced outer diameter for secure power delivery. It operates at a Rated Speed: 4,500 min^-1 and accelerates up to Max Speed: 15,000 min^-1 without compromise. Mechanical output delivers a Rated Torque: 15 Nm and Rated Power: 7 kW, while the Moment of Inertia: 0.0033 kgm^2 underpins rapid dynamic response. Weighing 11.2 kg, the stator balances mass and performance in compact drive systems.

Engineers benefit from the stator’s compatibility with frameless motor housings, simplifying mechanical coupling and alignment. The Aluminum Cooling Jacket paired with liquid cooling maintains optimal temperatures under peak loads, enhancing reliability and service life. For safe handling and storage, the unit is rated for ambient conditions from –20 °C to 80 °C and must be transported upright using the specified ring screw. This robust design makes the 1MS105N-4A-A1 ideally suited to high-speed spindles, precision robotics, and dynamic manufacturing equipment.
