Product Description:

Bosch Rexroth Indramat manufactures the MAC090A-1-ZD-2-C/110-B-1/S001 servo motor within the MAC AC Servo Motors series. The unit is designed for analog drive systems where a synchronous AC machine must deliver repeatable torque and speed commands issued by legacy motion controllers. By converting amplifier output into mechanical rotation, it automates indexing, web transport, and general material-handling stages that require accurate shaft regulation across extended duty cycles.

An external blower operates on 230 V AC and forces air along the frame to provide axial surface cooling, so the motor can withstand continuous thermal loading without exceeding insulation limits. The stator stack is held concentric by a 110 mm centering shoulder that mates directly with precision mounting flanges and minimizes runout. At rated excitation, the rotor reaches 1500 rpm, a speed suited to drive chains that synchronize with standard gearbox ratios and line frequencies. The ZD winding code indicates resistance, inductance, and back-EMF values compatible with the MAC power modules used in printing presses and flow-wrapper machines.

Velocity feedback is supplied through tacho feedback, allowing an analog controller to maintain speed linearity by comparing reference and actual voltages. The tacho generator produces 3 V/1000 rpm, giving sufficient signal strength for low-noise regulation over the entire operating range. Mains and phase conductors terminate through a connector on side B, simplifying cable routing in cabinets where service clearance is limited on the opposite end. A standard blocking brake holds the shaft whenever the drive is disabled, preventing vertical or inertia-dominated loads from drifting once power is removed. The motor works with analog control hardware used in established printing, packaging, and material-handling systems.
