Product Description:

The R2EA04008FCP00 is a servo motor built by Sanyo Denki and included in the R SANMOTION Servo Motors series. It is a medium-inertia rotary unit intended for positioning and speed control tasks in automated assembly cells, packaging lines, and other motion-control equipment. The model uses a battery-backed absolute encoder for feedback and includes a 24 VDC holding brake that locks the shaft whenever power is removed, allowing secure retention of vertical or suspended loads.

Mechanical integration is simplified by the 40 mm flange, and power is supplied from a 100 V single-phase line, so the motor pairs with compact drives in low-voltage cabinets. Under continuous duty, it delivers 80 W at a rated shaft speed of 3000 rpm, producing a steady 0.255 N·m of torque while drawing 1.3 Arms. The 2.9 Ω phase resistance limits startup current and supports thermal balance, while the 7.7 mV/rpm voltage constant indicates the back electromotive force that the drive must overcome during acceleration. A straight output shaft transmits torque without the backlash associated with a geared output. The attached cable eliminates the need for motor-mounted connectors and reduces the installation depth required for wiring.

In intermittent operation, the rotor can reach a maximum speed of 6000 rpm, doubling the continuous rating for short positioning moves. During these peaks, the shaft tolerates up to 0.86 N·m of stall torque, providing reserve force for rapid indexing and brief load changes. The electromagnetic design provides a torque constant of 0.22 N·m/Arms, allowing the control amplifier to calculate output torque from phase current. An IP67 housing prevents dust ingress and protects against temporary immersion under applicable test conditions. This enclosure supports operation in washdown areas and other locations where the motor may encounter water, dust, or airborne contaminants.
