Product Description:

The MAC090A-0-ZD-4-C/110-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is used in numerically controlled machining centers, pick-and-place gantries, and material-handling axes where repeatable rotary motion is required. The unit converts controlled electrical power into mechanical rotation so automated equipment can maintain speed and position under closed-loop control. This operating role suits machinery that depends on steady response during positioning, transfer, and synchronized motion tasks.

A centering flange of 110 mm aligns the housing with adjacent mechanics and supports concentric load transfer. Heat is removed by natural convection, which eliminates auxiliary fans and allows cabinet-mounted operation. The motor's rated operating speed is 1500 rpm, giving stable velocity for applications that require moderate but constant shaft speed. A built-in DC tachogenerator produces 3 V/1000 rpm, providing proportional feedback to the drive for analog speed regulation. For higher resolution or position capture, the motor can use incremental or absolute encoder feedback so the sensing method can match system accuracy targets. Power conductors exit through a connector on side A, which guides cable routing toward the designated machine face and keeps service loops clear of moving parts.

Winding code ZD identifies the stator impedance and torque constant used by the coordinating amplifier. The motor has no blocking brake, so stationary loads must be secured by mechanical locks or maintained by continuous drive torque during a power interruption. Tacho performance is listed as standard quality, which is suitable for general-purpose speed loops. The designation motor for analog drives confirms that the electrical interface relies on analog current or voltage commands rather than fully digital fieldbus control. This makes the motor suitable for use with older Rexroth drive cabinets that remain common in many production lines.
