Product Description:

The MAF100B-0250-FQ-S2-AH0-05-N1 is an asynchronous housing motor manufactured by Bosch Rexroth Indramat within the MAF IndraDyn Asynchronous Motors series. Engineered for flange integration inside automated machinery, the unit converts electrical energy into rotational motion for conveyors, spindles, and other duty cycles where constant torque and controlled heating are required. A molded connector on the A-side carries the three-phase supply, and flange mounting aligns the housing to machine frames without extra brackets.

Heat is removed by the motor’s liquid cooling circuit, which circulates coolant through an internal jacket. The coolant connection uses a 1/4 inch thread, which simplifies hose selection and helps maintain steady flow. The sealed enclosure meets IP65 protection, guarding internal components against dust and low-pressure water jets. With a rated rotor speed of 2500 rpm, compatible drive controllers can use a broad constant-torque range. Feedback travels over the EnDat2.1 serial link, allowing synchronized position and diagnostic data with minimal wiring. A plain shaft transfers torque directly to couplings or pulleys.

The motor’s feedback system includes a single-turn absolute encoder with 2048 increments, which supports fine position reporting for tight speed loops. That sensor operates on 7–12 V, matching common servo drive supply rails without requiring an auxiliary converter. Thermal endurance is provided by insulation class F, which permits winding temperatures up to 155 °C. Mechanical behavior complies with DIN EN 60034-14, and vibration level A helps limit transmitted oscillation. The unit does not include a holding brake or a shaft sealing ring, which reduces rotating inertia when external devices handle restraint and sealing. Standard bearings support the rotor, while frame size 100 and length code B keep the motor compact for cabinets maintained between 0 and 40 °C ambient. Winding code 0250 matches the stator to drives that use this torque-speed profile.
