YVF2 variable-speed induction motor

CATALOGUE OVERVIEW

About this motor series

Shangyang's YVF2 range is intended for machinery requiring adjustable speed through an electronic frequency converter. The manufacturer lists frame heights 80–355 mm, output ratings of 0.55–315 kW, class F insulation and S1 duty. Its product description gives a 150–2750 rpm range for four-pole applications; that statement should not be transferred unchanged to other pole counts. The technical sheet also identifies independent ventilation, which is relevant when sustaining load at low speed. Applications named by the manufacturer include transport, metallurgy, textiles, chemical equipment, fans and pumps. A purchasing enquiry should define the continuous torque demand across the required speed range, the available supply and converter type, plus the fan supply, mounting dimensions and enclosure option needed on site.
