Product Description:

The MAC090A-0-ZD-4-C/110-A-0/WI504L V/S005 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Supplied for analog drive systems, the unit delivers closed-loop torque and speed control to actuators, gantries, and transfer stations that rely on precise electrical positioning in continuous industrial duty cycles. With its integrated feedback and balanced rotor geometry, the motor supports repeatable motion sequences in multi-axis assemblies. This type of motor is well suited for applications that require accurate starts, stops, and smooth speed transitions during repeated production cycles.

The motor uses winding code ZD, which is matched to drive amplifiers that require moderate current at rated flux. Under nominal excitation, the rotor reaches 1500 rpm, which establishes the base speed for velocity control. Heat produced in the stator is dissipated by natural convection, eliminating the need for external blowers and simplifying cabinet layout. The housing aligns to machinery through a 110 mm centering diameter, which provides a repeatable pilot fit for coaxial mounting. The motor has no blocking brake, so load holding must be provided by drive torque or external mechanical restraints when power is removed.

A tachogenerator delivers 3 V/1000 rpm, providing proportional speed feedback to the analog controller during operation. The power conductors exit through a connector on side A, which keeps cabling on a single plane and can simplify routing near the motor. Position data is supplied by an incremental encoder mounted in the standard rear interface. The motor uses a factory-installed tacho feedback plus encoder arrangement, which supports fine velocity trimming and position referencing functions. The tacho quality is standard, which is suitable for general automation lines that do not require extended linearity grades.
