Product Description:

The MAC063A-0-ES-4-C/095-B-0/WI522LV is a brushless AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts drive-amplifier commands into controlled rotary motion for positioning and speed-regulated machine axes in production equipment. Its compact A-length housing fits into confined machine spaces while providing the torque density required for responsive automation. The brushless design supports repeated operating cycles without the commutator wear associated with brushed motors.

The motor has a frame size of 063, and its centering flange measures 95 mm, providing an accurate pilot fit for gearboxes or mounting brackets. Under rated electrical excitation, the rotor turns at 3500 rpm, making it suitable for light- to medium-inertia loads that require rapid response. Heat is removed by natural convection, so installation must permit unobstructed airflow around the housing. Power is supplied through a connector on side B, simplifying cable routing when the opposite side of the motor is positioned near a machine panel. The centering flange supports accurate alignment between the motor shaft and the connected mechanical assembly, helping reduce coupling stress during operation.

The ES winding establishes the phase resistance and inductance presented to the drive amplifier. Position control relies on an incremental encoder mounted in the standard orientation, allowing the connected controller to track shaft movement through encoder pulses. A standard-quality tachogenerator provides speed feedback for analog control loops and delivers 1.5 V per 1000 rpm in proportion to shaft speed. The motor has no blocking brake, so an external holding device or drive-applied torque is necessary if the shaft must remain stationary after motor power is removed. Separate position and speed feedback signals allow the drive system to regulate motion while responding to changes in load and commanded velocity.
