Product Description:

The MAC093C-0FS-4-C/110-A-2/DI522LV/S004 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it translates continuous command voltages from legacy controllers into tightly regulated shaft rotation for gantries, tool heads, and indexing tables. The frame follows the 093 size code with a C length stack, and heat produced during operation is removed by natural convection, allowing cabinet integration without auxiliary blowers. Its winding layout suits medium-inertia loads that need stable speed control, repeatable positioning, and predictable thermal behavior during frequent starts and stops. Because cooling is passive, the housing can be used in machine sections where airflow is limited and fan maintenance is undesirable.

At standstill, the motor delivers a continuous torque of 19.5 Nm while drawing 35 A, which sets the thermal baseline for static holding under load. Its rated running speed is 3000 rpm, and the electromagnetic system has a torque constant of 0.579 Nm/A, so commanded current corresponds directly to output torque across normal operating ranges. The stator has a winding inductance of 2.9 mH and a winding resistance of 0.175 ohms; together these values affect current response, control stability, and copper heating. The combination is useful where analog servo amplifiers must maintain smooth motion without abrupt current swings during reversals or short dwell periods.

For short-duration overloads, the motor withstands a peak pulse current of 173 A, which supports rapid acceleration and brief torque surges during direction changes. An integrated brake provides 14 Nm of static torque to hold the shaft when drive power is removed, and the feedback system uses a shock-damped incremental encoder with TTL output for precise speed and position tracking. The encoder signal also gives the analog drive a stable basis for low-speed regulation and repeatable stopping accuracy. The assembly has a thermal time constant of 50 min, so internal temperature rises gradually instead of spiking immediately during changing duty cycles. This response gives the connected drive more time to reduce current or adjust motion before the winding approaches its thermal limit.
