Product Description:

The MAC025B-0-ZS-2-E/040-C-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Intended for analog drive systems, it supplies closed-loop torque and velocity control to compact automation axes. The motor converts sinusoidal phase currents into controlled mechanical rotation, making it suitable for assembly machines, small pick-and-place heads, electronic component insertion equipment, and similar applications that require high speed and repeatable positioning. Its aluminum housing promotes heat dissipation while keeping mass low, and the shaft can be coupled directly to belt or planetary transmissions in space-constrained frames.

At standstill, the unit delivers a continuous torque of 0.60 Nm when the windings draw 2.80 A. Electromagnetic conversion follows a torque constant of 0.220 Nm/A, so the drive controller can estimate shaft load directly from the phase current. During motion, the rotor reaches a rated speed of 10,000 rpm, enabling rapid point-to-point movement on short-stroke axes. A low rotor inertia of 3.2 × 10⁻⁵ kg·m² limits stored kinetic energy, allowing quick deceleration without excessive regeneration into the DC bus.

Thermal management relies on natural convection, so no external fan or liquid circuit is required. Position and speed are monitored through integrated tacho feedback that provides 0.75 V/1000 rpm, giving the analog drive continuous velocity information. Mechanical integration uses a B05 flange pattern, and power conductors leave through a keyed connector on side A. The motor is supplied without a blocking brake, so static holding torque must come from the drive or an external latching device. The motor has a frame size of 025 and a frame length of B, allowing it to fit compact machine layouts while supporting rapid motion.
