1MR241H-A098

The Bosch Rexroth Indramat 1MR241H-A098 is part of the 1MB High-Speed Asynchronous Motors series, engineered for high-speed and precision applications. The motor features a shaft rotor inside diameter of 98 mm and a frame length designated as H. With a motor size of 241, this asynchronous frameless rotor delivers a robust solution for applications requiring compact design and high rotational speeds. The primary function of the 1MR241H-A098 is to convert electrical input into consistent rotational motion with minimal vibration, making it ideal for spindle drives, high-speed milling spindles, and precision machining centers.

The 1MR241H-A098 offers a rated torque of 202 Nm at a nominal speed of 1800 RPM, drawing a rated current of 75.5 A. Insulated to class F, the rotor maintains reliable performance even in humid environments. It employs a liquid cooling system with a maximum inlet pressure of 3 bar and an inlet temperature range of 10 to 40 °C, ensuring thermal stability under continuous high-load conditions. Depending on the stator winding code (6C, 6D, or 6G), power loss varies between 3 to 4.5 kW, and inductance ranges from 1 to 5.05 mH. In the 6G winding, the rotor features three pole pairs and a torque constant of 6.51 Nm/A, highlighting its efficient electromechanical conversion.

Additional features include a shipment temperature tolerance from –20 to +80 °C and a service operating range of 0 to +40 °C, ensuring durability in diverse environments. With a rotor mass of 39 kg, the 1MR241H-A098 maintains structural integrity under dynamic loads. The absence of an integrated brake offers system design flexibility, while a one-year warranty from the distributor underscores product reliability. In industrial contexts, this high-speed asynchronous motor enhances process efficiency, reduces maintenance downtime, and delivers consistent torque output for precision-driven manufacturing operations.
