Product Description:

The MAC063A-0-ES-4-C/095-A-0/WI511LV is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts current commands from a drive amplifier into controlled torque and speed for positioning axes in industrial machinery. The motor integrates into closed-loop motion systems that require precise velocity and incremental position data for packaging, material handling, and tooling stations. Its compact frame helps reduce the space required around moving assemblies, while the integrated tachogenerator and encoder provide the feedback needed for responsive motion control. These feedback channels allow the connected analog amplifier to monitor shaft movement and correct deviations caused by changing loads.

The motor has a rated speed of 3500 rpm, allowing moderate-torque applications to reach the commanded speed quickly. A 95 mm centering pilot aligns the motor flange with a gearbox or machine mounting plate. Heat generated by the stator is removed through natural convection, eliminating the need for an auxiliary blower and reducing the number of cooling components around the motor. Power conductors pass through a connector on side A, allowing cables to be routed toward the drive side of the machine. The tachogenerator produces 1.5 V/1000 rpm, providing an analog velocity signal for proportional-integral control within a compatible drive amplifier. This signal changes in relation to shaft speed, giving the control loop continuous velocity information during acceleration, steady operation, and deceleration.

The mechanical package has motor size 063 and length code A, resulting in a short rotor stack and low mass for rapid acceleration. The motor has no blocking brake, so an external mechanism or drive-generated torque must hold the axis at rest. Winding designation ES indicates the resistance and inductance values used by compatible MAC analog amplifiers. Position sensing is provided by an incremental encoder with standard mounting, which returns displacement information to the controller while the tachogenerator supplies velocity feedback. The standard mounting arrangement supports proper encoder alignment within the motor assembly without requiring a separate external feedback device. Tacho quality is standard, making the feedback arrangement suitable for established analog control systems that process separate velocity and incremental position signals.
