The MAD100B-0250-SA-S2-FH0-05-N1 is a servo motor produced by Bosch Rexroth Indramat within the MAD IndraDyn A Motors series. Designed for positioning and speed control in automated machinery, the unit converts electrical drive commands into rotary motion for conveyors, pick-and-place axes, and indexing tables. When paired with a suitable drive controller, it contributes to closed-loop regulation that keeps positional accuracy consistent despite load changes and duty-cycle variations.

Heat generated in the stator windings is removed by an integrated axial fan, so the motor can sustain rated current without external cooling. Rotor position feedback is supplied through a singleturn absolute encoder EnDat2.1, allowing immediate position availability after power-up. Power and signal conductors terminate inside a sealed terminal box, which protects connections from coolant splash. The housing is prepared for flange mounting, ensuring direct alignment with gearboxes or machine plates. A smooth shaft without a shaft seal reduces friction and is intended for clean environments, while vibration grade R defines balancing suitable for general automation duty.

Internally, standard bearings handle radial and axial loads that correspond to the mechanical envelope of frame size 100. The lamination stack follows frame length B, giving torque density appropriate for medium-inertia axes. All cables leave on the A-side, helping machine builders route harnesses away from moving tooling on right-hand layouts. Electromagnetic behavior is set by winding code 0250, which defines resistance, inductance, and thermal constants expected by the matching drive. Because the motor is supplied without a holding brake, static load retention must be provided by the drive’s torque or an external clamp. Together these construction details establish a stable platform for repetitive positioning cycles across a broad operating duration.
