Product Description:

The MAC025C-0-QS-2-E/040-C-0/S006 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is a compact motor for analog drives that delivers precise shaft rotation for positioning or velocity control in small automation axes, pick-and-place heads, and light material-handling devices. The unit has no integrated encoder and instead relies on its built-in tachogenerator for feedback, while its lack of a blocking brake requires external holding support when the shaft must remain stationary.

The motor develops a standstill torque of 0.90 Nm while drawing a standstill current of 4.00 A. Together, these ratings indicate the continuous holding capability available without exceeding the motor’s thermal limits. Its electromagnetic design produces a torque constant of 0.230 Nm/A, so each ampere commanded by the drive produces approximately 0.23 newton-meter of shaft torque. Once in motion, the rotor can reach a nominal speed of 10000 rpm, allowing high cycle rates for indexing mechanisms or spindle attachments. The internal tachogenerator provides a feedback gradient of 0.75 V/1000 rpm, giving the analog controller a proportional voltage for closed-loop speed regulation without an additional sensor channel.

The lightweight rotor has an inertia of 0.41 × 10^-4 kg·m², supporting fast acceleration and minimal overshoot during duty cycles with frequent reversals. Heat is dissipated through natural convection, so no external blower or liquid-cooling circuit is required. The flange uses the B05 mounting style, providing a pilot diameter and bolt circle for direct coupling to gearheads or machine plates. Power conductors exit through a connector with a cable end on side A, keeping the wiring bundle on the drive side of the machine and simplifying harness routing in compact installations.
