Product Description:

The MAC063A-0-ES-4-C/095-A-1/WA608XX is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it supplies precise torque and velocity for motion axes that require continuous positioning accuracy. Its electromechanical design and compact footprint allow it to connect to gear stages or belt transmissions in packaging equipment, handling systems, and other automated machinery. The encoder-ready rear housing supports position-sensing options when an application requires more detailed motion feedback. Its connectors also simplify cable routing in multi-axis assemblies where several motors operate near one another.

The frame code of 063 identifies the stator diameter and establishes the mechanical envelope for compatible mounting flanges, while length code A keeps the housing depth compact. During continuous duty, the rotor can operate at 3500 rpm, which suits medium-inertia loads controlled by analog amplifiers. A centering pilot of 95 mm supports concentric alignment with a gearbox and helps prevent radial runout at the coupling. Heat is removed through natural convection, so the housing requires unobstructed airflow to keep the winding temperature within its operating limits. This cooling method eliminates the need for an external fan and reduces the number of auxiliary components around the motor. The integral standard blocking brake provides 3 Nm of holding torque, allowing a stationary axis to remain secured when power to the amplifier is disabled.

The armature uses winding code ES, which indicates resistance and inductance values matched to compatible Bosch Rexroth analog amplifiers in the 60 V class. Speed monitoring is supported by a standard-quality tacho generator with an output of 1.5 V per 1000 rpm, providing the controller with a voltage that changes in proportion to rotor velocity. All power conductors use a connector on side A, keeping service loops on one face of the machine frame and simplifying access to the cable connection. For higher-resolution motion loops, the rear housing supports tacho feedback with an incremental or absolute encoder supplied as an attachment set. This arrangement provides position data without requiring an external mounting adapter. The available feedback hardware allows the connected drive to monitor shaft movement while maintaining the motor’s compact installation profile.
