Product Description:

The MAC90B-0-JD-1-X/110-A-0/J2500/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drives, the motor converts drive commands into precise rotary motion for positioning tasks on assembly lines, packaging machines, and material-handling equipment. Its mechanical interface, electrical constants, and feedback accommodations allow the drive controller to maintain position accuracy while the system operates under variable loads.

The motor uses a centering diameter of 110 mm and a flange measuring 130 mm, dimensions that fit standard IEC mounting faces on gearboxes or machine plates. With a mass of 18 kg, the motor requires secure support in the machine structure, and that mass can also help reduce vibration. Under rated conditions, the rotor reaches 3000 rpm, giving the drive a broad usable speed range. The housing is sealed to IP65, which keeps out dust and resists water jets around the windings and resolver housing. A 24 mm shaft couples power to the load, and rotor inertia of 0.0036 kg·m² helps limit overshoot during rapid reversals.

Torque generation characteristics govern electrical sizing. At standstill, the motor produces 6.7 Nm while drawing 18.2 A, so the drive can use this value when holding loads at zero speed. The torque constant of 0.41 Nm/A links commanded current to output torque. For short transients, the windings withstand a peak pulse of 137 A, allowing quick acceleration before thermal limits intervene. Those limits are modeled by a time constant of 60 min, which shows that the frame temperature changes slowly and supports intermittent overload duty. A continuous phase current of 14.8 A, a winding inductance of 2.0 mH, and a resistance of 0.38 Ω shape the current loop response that the analog drive must achieve.
