MAF100D-0250-FQ-M2-AH0-35-N1

The MAF100D-0250-FQ-M2-AH0-35-N1 is an asynchronous AC motor produced by Bosch Rexroth Indramat in the MAF IndraDyn Asynchronous Motors series. It serves as a prime mover for servo drives and spindle assemblies where adjustable speed and continuous duty are required. Because the rotor is of the squirrel-cage type, no separate excitation wiring is needed, which minimizes maintenance and simplifies cabling. The frame-size 100 housing supports flange mounting to standardized gearboxes or machine plates inside automated production lines.

At its continuous operating point the motor delivers 19.6 kW of mechanical output while drawing a nominal 45.8 A from the inverter. This rating is reached at 2500 rpm, producing a shaft load of 75 Nm without thermal derating. For short bursts the design can supply up to 177.5 Nm, providing headroom for acceleration or brief overloads. A current-to-torque gradient of 1.55 Nm/A links drive current to torque generation, enabling precise closed-loop control. Together these electrical and mechanical limits define the working envelope used when sizing gear ratios and evaluating thermal balance in an automation cell.

The electromagnetic geometry employs 3 pole pairs, so the inverter’s electrical frequency equals three times the mechanical speed for field-oriented control. An enclosure rating of IP65 seals the stator against dust ingress and low-pressure water jets, supporting installation outside a control cabinet. Dynamic response is aided by a rotor inertia of 0.032 kg·m², which balances quick acceleration with smooth running in medium-mass loads. Thermal behavior is characterized by a 10 min time constant, giving the control system a predictable window to manage heating during cyclic or intermittent duty.
