Product Description:

The MAC90C-2-KD-1-B/110-A-0/J625/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. In closed-loop motion systems, this unit couples with analog drives to convert electrical commands into precise shaft rotation for indexing tables, packaging stations, and other positioning axes. By supplying steady torque while also delivering rapid transients, the motor fulfills key positioning tasks within industrial automation and serves as an electromechanical actuator where stable speed control and repeatable acceleration are required.

Heat generated during service is removed through natural convection, so the installation must allow free airflow around the housing. Under rated excitation, the stator draws a phase current of 13.9 A, and the motor reaches a nominal shaft speed of 2000 rpm. For static holding or low-speed indexing, the rotor can exert a standstill torque of 10.4 Nm. The windings have an inductance of 3.6 mH, while the winding resistance is 0.60 Ω, which affects copper losses and the voltage demanded from the analog drive. Conductors down to 1.5 mm² may be crimped with the INS 108/02 terminal, and feedback lines can be routed with the INK 650 shielded cable to reduce electrical noise.

During acceleration, the drive supplies a pulse current of 125 A, overcoming the rotor’s 53 × 10⁻⁴ kg·m² inertia to achieve target speed quickly. Electromechanical conversion is supported by a torque constant of 0.68 Nm/A, while continuous stall duty requires 17.0 A when maximum steady load is needed. The motor weighs 23 kg, adding mass that helps damp vibration once bolted to a machine frame. A 60-minute thermal time constant permits intermittent overloads without immediate overheating, supporting variable duty cycles. Where full shielding is unnecessary, the INK 250 unshielded power cable can be used to keep connections compatible with the analog controller environment.
