Product Description:

The MAC63C-1-MS-2-C/95-B-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it works with servo amplifiers that regulate armature current to control position and velocity in automated machinery such as carton erectors and small transfer tables. Its compact frame allows installation in machinery with limited space, while the cooling system removes heat generated during operation. Integrated speed feedback supplies the signal needed by the amplifier to correct velocity deviations as the mechanical load changes.

The motor reaches a nominal operating speed of 3500 rpm, supporting moderate-to-high throughput on production axes without requiring gear reduction. At standstill, it produces 2.7 Nm of torque while drawing 5.3 A, allowing the energized motor to hold vertical or high-inertia loads. Its torque constant is 0.51 Nm/A, providing a direct relationship between armature current and motor torque for analog drive control. The winding has a phase resistance of 2.8 ohms, which affects copper losses during continuous operation. Its winding inductance is 3.2 mH, which moderates the rate of current change during rapid command transitions. Heat from the stator passes through axial surface-cooling fins positioned in the blower’s airflow along the housing.

High-demand movements are supported by a peak pulse current of 22 A, permitting brief bursts of acceleration within the motor’s operating limits. The rotor moment of inertia is 4.0 × 10⁻⁴ kg·m², enabling quick speed and direction changes when commanded by the drive. A housing blower powered by 230 V AC maintains airflow across the motor during operation, and the winding has a thermal time constant of 15 minutes. Torque is transmitted through a shaft key measuring 5 × 5 × 22 mm, while a 95 mm pilot centers the motor accurately on the mounting surface. The unit has an overall length of 272 mm, which must be considered when allowing space for the housing and cable routing. Tacho feedback provides 1.5 V/1000 rpm, giving the analog drive a linear signal for closed-loop speed regulation.
