R88M-UE40030V-S1

The R88M-UE40030V-S1 model from Omron is an AC servo motor tailored for efficient operation. It has a maximum output power of 400 watts and is constructed with a straight shaft configuration that includes keys but no brake. Designed to work seamlessly with servo drivers such as the R88D-UEP12H or R88D-UEP12V, this unit is essential for modern motion control applications.

Weighing approximately 1.7 kilograms, this motor features a nominal rotational speed of 3,000 revolutions per minute (RPM) that can ramp up to a peak speed of 4,500 RPM. For applications with significant demands, it offers a peak torque rating of 3.82 newton meters, and at rated load, it maintains a torque output of 1.27 newton meters.

The efficient design results in a rapid mechanical response time of just 0.3 milliseconds, enhancing its ability to manage dynamic tasks. The back electromotive force of the motor is measured at 18.6 millivolts per RPM, reinforcing its responsiveness in various conditions. With a continuous current rating of 2.6 amperes (rms) and a maximum capacity of 8.0 amperes (rms), it supports high-efficiency performance. Furthermore, the motor’s rotational inertia is calculated at 1.91 × 10⁻⁵ kilogram-meter squared, which aids in maintaining stable operation during speed changes. The torque sensitivity is specified at 0.533 newton-meters per ampere, ensuring optimal torque generation relative to the current input.
