Product Description:

Bosch Rexroth Indramat manufactures the MAC090A-0-ZD-4-C/110-A-1 as part of the MAC AC Servo Motors series. The unit is an AC servo motor that transmits controlled torque and speed to automated axes driven by analog amplifiers. Within industrial automation, it converts electrical commands into precisely metered mechanical motion, allowing synchronized positioning on conveyors, pick-and-place gantries, and rotary tables. Permanent magnets on the rotor and integrated speed feedback enable the drive controller to close velocity and position loops without extra mechanical sensors. This arrangement supports repeatable motion during frequent starts, stops, and speed changes.

Mechanical alignment is handled by a centering pilot of 110 mm, which seats the motor flange concentrically to attached gearboxes and helps prevent shaft offset. At its rated speed of 1500 rpm, the electromagnetic system produces nominal torque while remaining within the thermal limits of natural convection cooling, so no external blower or liquid circuit is required. Power is supplied through a connector on side A, which helps simplify cable routing inside cramped enclosures. For velocity verification, the integral tacho generator outputs 3 V/1000 rpm, a proportional signal that the controller reads to regulate dynamic acceleration and deceleration. This feedback signal helps the axis maintain stable response during changing load conditions.

The motor ships with a blocking brake in the standard version, allowing vertical loads to be held when power is off. Winding code ZD identifies the copper fill and impedance values used for this frame size, giving the drive predictable current draw during starts and reversals. Position data reach the amplifier through an incremental or absolute encoder with tacho feedback, and the signal quality is rated standard for consistent pulse accuracy. The unit is a motor for analog drives, so it can operate with legacy ±10 V control systems. This makes it suitable for machines that continue to use established analog motion hardware.
