Product Description:

The MAC063A-0-ES-4-C/095-A-1/WI524LV is a servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive-amplifier current into precise mechanical rotation for positioning or speed-regulated tasks in industrial automation cells. The unit has frame size 063 and motor length A, relies on natural convection for cooling, and incorporates tacho feedback together with encoder signals to close the control loop when space is limited and forced airflow is unavailable.

At standstill, the motor can deliver 0.8 Nm of continuous torque while drawing 2.2 A of continuous current, reflecting the losses that the housing can dissipate through its natural-convection surface. The motor has a torque constant of 0.370 Nm/A, so each ampere supplied by the analog drive produces proportional shaft torque. During rated operation, the rotor reaches 3500 rpm, making the motor suitable for machinery that needs moderate speed without gear reduction. The laminated stator carries windings with 9.1 mH of inductance and 9.6 Ω of resistance at 20 °C, which affect the current rise time. A thermal time constant of 30 minutes indicates how long the frame takes to reach 63% of its final temperature rise and permits intermittent overloads within the applicable operating limits.

Peak demand is supported by a 12 A pulse current, enabling rapid acceleration before the controller returns the motor to its nominal load. A standard blocking brake provides 3 Nm of holding torque, operates from 24 VDC, and engages when its power is removed. The rotor inertia of 2.4 × 10⁻⁴ kg·m² supports quick reversals, and mounting is centered on a 95 mm pilot. Power enters through a connector on side A, while the ES winding code identifies the electrical configuration. Position feedback comes from an incremental encoder with standard mounting, and the tachogenerator delivers 1.5 V per 1000 rpm with standard tacho quality for velocity control loops. The motor has a total mass of 3.2 kg, allowing it to fit compact machine axes without adding excessive moving weight.
