Product Description:

The MAC063B-0-JS-4-C/095-B-0/WI517LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed for analog drives, it converts command voltages from servo amplifiers into controlled torque and velocity for closed-loop motion in handling, packaging, and processing lines. This makes it suitable for axes that need repeatable starts, stops, and speed changes under varying load. Its feedback system combines a tachometer signal with an incremental encoder so the drive can monitor speed and position during operation.

The unit’s nominal shaft speed reaches 6000 rpm, giving sufficient headroom for rapid positioning moves. Heat generated during operation is removed by natural convection, so no external fan or liquid circuit is required, and a centering diameter of 95 mm provides concentric location in the machine flange. Torque is transmitted through a DIN 6885 keyway that matches standard couplings, and electrical power is routed through a connector on side B to simplify cable runs in tight cabinets. The motor is supplied without a blocking brake, so mechanical holding must be provided externally when power is removed. When the axis must remain fixed at standstill, holding torque has to come from the drive or external mechanics.

The tachometer produces 1.5 V/1000 rpm, generating a proportional signal for the analog regulator. The electromagnetic circuit uses the JS winding code, which corresponds to the resistance and inductance expected by the matching drive. Overall dimensions correspond to the 063 motor size and the motor length B classification, helping the unit fit compact multi-axis assemblies where mounting space is limited. Position sensing is handled by an incremental encoder with standard mounting hardware, providing digital resolution when an application requires finer positioning than the analog tachometer alone.
