Variable Frequency Three-phaseAsynchronous Motor

The YSP-225S-4 is a mid-size model from the JEYSP product line, tailor-made industrial Three-Phase Motors engineered to eliminate harmonic damage caused by VFD operation. Unlike regular electric motors, these customized Variable Speed Motors are upgraded from conventional universal Induction Motors and stand out as practical, power-saving High-Efficiency Motors for factories requiring flexible speed regulation. Spanning power outputs from 0.75kW up to 315kW, this 4-pole motor adopts reinforced F-class insulated windings and dual IC411/IC416 external cooling blowers to maintain stable temperature even under prolonged low-speed running. It delivers consistent constant torque within 5Hz–50Hz for heavy startup loads, while switching to constant power mode from 50Hz to 100Hz for high-speed processing tasks. Users can select IP44, IP54 or IP55 protection grades to fit damp, dusty metallurgy and textile workshops. Running under S1 continuous duty, these Variable Speed Motors generate mi…
