Product Description:

The MAC90C-0-GD-4C/110-A-1/WI524/S001 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat and is classified as a motor for analog drives. Within an automation cell, it converts drive commands into controlled shaft motion for positioning tasks on machine tools, packaging axes, and handling equipment. Its housing relies on natural convection for heat removal, so the unit can be installed without forced-air ducts when cabinet airflow is constrained. This arrangement suits applications that need accurate motion control while keeping the motor package mechanically simple.

This motor delivers a nominal shaft speed of 3000 rpm, allowing direct coupling to gear stages sized for mid-range production lines. At standstill, it can apply 9.6 Nm of torque while drawing a steady 24.8 A, which indicates the continuous load the drive must support during static holding cycles. The electromagnetic conversion rate is set by a torque constant of 0.43 Nm/A, so each ampere commanded by the analog amplifier adds predictable turning force. When power is removed, the integrated holding brake applies 6.5 Nm to help prevent axis drift, and the 110 mm centering diameter aligns the flange on standardized mounting surfaces.

Short accelerations are handled by a peak pulse current of 196 A, giving extra current capacity for rapid index moves before thermal limits are reached. Internal heat rises gradually because the windings have a thermal time constant of 60 min, which helps the motor tolerate intermittent duty without immediate derating. The brake engages after a 20 ms clamping delay and releases after a 60 ms lag. A standard tacho generator provides speed feedback to the analog controller, while the winding inductance and resistance support stable current-loop behavior during changes in load and speed.
