Product Description:

The MAC071C-0-JS-4-C/095-A-2/WI522LV is a motor for analog drives produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It converts electrical power from legacy drive amplifiers into rotary motion for positioning and speed-controlled tasks in automated machinery. Its compact servo design supports repeatable response in transfer systems, packaging equipment, and other machines that rely on stable motion over frequent duty cycles. In servo applications, it works with an external amplifier that regulates current and uses returned feedback signals to correct speed changes caused by varying loads. Integrated feedback and a holding function allow the motor to support controlled movement during operation and secure stopping when power is removed.

Thermal management relies on natural convection, so installation should leave clearance for unobstructed airflow around the housing. Because no fan is present, ambient heat has a direct effect on winding temperature, so the system must remain within the permissible drive limits. This cooling method keeps the housing simple and avoids additional airflow hardware. The integrated brake can hold up to 6.5 Nm of torque, preventing axis drift when power is removed. A centering shoulder of 95 mm aligns the flange with mating parts and helps maintain concentricity. Under rated excitation, the shaft reaches 2000 rpm, and the tacho generator supplies 3 V/1000 rpm for real-time speed feedback to compatible analog controllers.

The motor has size 071 and length code C, giving it a compact frame that helps keep inertia low for responsive axis motion. The stator uses winding code JS, which matches the electrical characteristics expected by compatible analog amplifiers. Power enters through a connector on side A, which supports straightforward cable routing along the machine structure. Position data is produced by an incremental encoder with standard mounting, allowing the control system to monitor shaft movement during operation. These features suit machine layouts where cable exit direction and encoder arrangement need to remain consistent with existing drive hardware. The unit also includes a heavy-duty blocking brake for applications where the axis must remain stationary during stops or power loss.
