Product Description:

The MAC093B-0-JS-4-C/110-A-1/W1520LV is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts controlled electrical energy into precise shaft rotation for positioning axes, feed spindles, and conveyor sections in automated plants. Its 093 frame and B length are matched to the flange interface, giving the unit a compact mechanical envelope for machines that need accurate motion without a large motor body. Integrated feedback and power connections allow direct installation with existing axis hardware. This layout also suits machine sections where installation space is limited and cable access must remain orderly.

The motor’s 093 frame accepts a centering pilot of 110 mm, giving accurate seating on the machine plate. Heat is removed through natural convection, so unobstructed airflow around the housing is necessary for continuous duty. Rated speed reaches 3000 rpm, supporting typical feed rates in metal-cutting and handling applications. Rotor position and velocity are reported by tachofeedback with an incremental or absolute encoder, allowing legacy analog speed loops to work alongside position control functions. Electrical behavior follows winding code JS, which indicates the phase resistance, inductance, and current values used when matching the motor to a compatible drive amplifier. The standard tacho quality supports stable speed signaling across the operating range.

A spring-applied, electrically released standard blocking brake holds the shaft whenever the drive is disabled, helping prevent load drift on vertical or suspended axes. Servo feedback generates 3 V/1000 rpm, delivering a proportional speed signal directly to analog regulators for closed-loop control. Power and feedback conductors exit through a connector on side A, which helps keep cable routing predictable when the motor is mounted with its shaft toward the workspace. This arrangement keeps the connection area on one side of the housing and reduces interference with nearby machine components.
