Product Description:

The MAC063A-0-ES-4-C/095-B-0/WI574LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for analog drives, where commanded current is converted into controlled shaft rotation for closed-loop speed and position tasks. Because the motor includes feedback functions, the paired amplifier can react to load changes and keep motion stable during indexing, conveying, and other repeatable machine movements. This makes the unit suitable for compact machine axes, conveyors, and light pick-and-place modules in industrial automation.

The housing seats on a centering flange that measures 95 mm in diameter, allowing precise alignment with gearboxes or mounting plates. Heat is removed through natural convection, so no external blower or liquid circuit is needed. Since cooling relies on the motor surface rather than auxiliary equipment, surrounding installation space can remain simple and compact. Under rated conditions, the rotor reaches 3500 rpm, which suits medium-inertia loads driven by analog amplifiers. Power conductors exit through a connector on side B, which helps keep the cable path clear of moving machine parts. A tachogenerator supplies 1.5 V/1000 rpm, and this linear signal gives the control loop a direct speed reference.

The motor uses size 063 with frame length A, which helps keep the overall envelope compact on multiaxis equipment. Winding code ES gives electrical characteristics that match standard MAC drive ratings. Position data is returned by an incremental encoder mounted with the standard flange, allowing the drive to monitor shaft movement for positioning functions. The motor is supplied with no blocking brake, so vertical loads must be held by drive torque or an external clamp when power is removed. Its WI feedback arrangement combines tacho and encoder signals, allowing the motor to provide both velocity and position information through one integrated feedback package.
