Product Description:

The MAC025A-0-WS-3-E/040-B-0 is a compact AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Built as a motor for analog drives, it converts continuous command voltages from a matching drive into proportional torque and speed for use in material-handling stations, small packaging equipment, light-duty manipulators, and other compact automated axes that require repeatable rotary motion without a large motor footprint. Its electromagnetic design supports stable positioning and velocity loops during frequent start-stop cycles while keeping inertia low for responsive motion profiles in multi-axis assemblies where fast acceleration and simple control architecture are both important.

Thermal dissipation is handled by natural convection, so the housing relies on surface area and ambient airflow rather than forced cooling hardware or an auxiliary fan. This cooling method keeps the motor mechanically simple and avoids the extra wiring associated with forced-air devices. The motor includes tacho feedback with a second shaft end; the tachogenerator supplies analog speed information, while the auxiliary shaft can be coupled to an external encoder or mechanical brake. The motor is supplied without a blocking brake, so any hold-position requirement must be met by the connected drive or by external clamping. Its dimensions use a length 025 stator stack and a frame size A, giving the unit a short overall body where mounting space is limited.

Power conductors enter through a connector on side B, which allows cable routing along the rear of the machine and keeps the power lead away from the feedback end. This arrangement also leaves the auxiliary shaft area unobstructed for coupled feedback or accessory hardware. The stator winding identified by code WS sets the motor's voltage constant and current demand so the matching analog amplifier can deliver rated torque without saturation under normal operating conditions. Because it is classified as a motor for analog drives, command inputs are proportional rather than digital pulses, which suits retrofit installations and control cabinets that use continuous reference signals instead of pulse trains or network-based command data.
