Product Description:

The MAC092B-0-QD-1-B/095-B-1/100625 is an AC servo motor from Bosch Rexroth Indramat in the MAC AC Servo Motors series. It is intended for use with analog drive controllers in industrial automation. The motor converts electrical commands from legacy velocity or torque loops into precise rotary motion so machine axes can position accurately or follow speed references without digital bus communication. This operating style is common on equipment that uses analog reference signals instead of networked motion control.

The motor can deliver a continuous torque of 3.0 Nm at standstill, so it can sustain static loads without overheating while current is held. Under a regulated DC supply, it reaches a top speed of 4700 rpm. When the DC bus is unregulated, the maximum speed drops to 4000 rpm, showing the effect of supply stability on available mechanical output. A rotor inertia of 16.0 kg·cm² provides a balance between acceleration response and smooth running during speed changes. Heat is removed through natural convection, so the housing should remain unobstructed and the ambient temperature should stay within the permitted operating range.

A centering diameter of 95 mm helps align the flange accurately with a gearbox or machine frame and keeps radial runout low. The motor uses incremental encoder feedback, so the connected drive must count the signal pulses to track shaft position during operation. Because the feedback is incremental, position information must be reestablished after power loss if the control system does not retain a reference. A standard blocking brake is fitted to hold the rotor when power is removed on vertical or biased axes. Power conductors enter through a connector on side B, which affects cable routing and the available clearance near adjacent machine parts.
