Product Description:

The MAC90A-0-ZD-2-C/110-A-0/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for integration with analog servo amplifiers, it converts drive commands into controlled mechanical motion for positioning, indexing, and speed-regulated processes on automated production lines. Its operating concept suits machines that require steady speed feedback and repeatable axis response during continuous industrial use.

The motor delivers a continuous torque of 3.7 Nm while drawing 8.1 A at rated load. With a torque constant of 0.51 Nm/A, the controller can calculate shaft torque directly from measured phase current. Rated speed reaches 2000 rpm, allowing moderate-speed axes used in packaging or material-handling machines. Short acceleration bursts are supported by a peak pulse current of 53 A, enabling rapid indexing without exceeding thermal limits. Cooling relies on natural convection, and the lack of an internal fan reduces maintenance needs. Standard tacho feedback delivers 3 V per 1000 rpm, supplying the analog drive with real-time velocity data.

Electrical dynamics are influenced by a phase inductance of 1.9 mH and a winding resistance of 1.85 Ohm, which affect current rise and power dissipation. The unit is intended for analog velocity and position loops, so stable electrical characteristics are important during changing load conditions. Thermal modeling uses a time constant of 45 min, meaning the winding temperature responds gradually to load changes, which is consistent with natural-convection cooling. Rotor inertia helps smooth speed variation during cutting or winding duties. Total motor mass is 12.5 kg, and the 110 mm centering diameter simplifies alignment with gearheads. The housing has no blocking brake, and the power and feedback connectors are positioned on side A for straightforward cable routing.
