Résumé : The three-phase induction motor has been adopted for the drive
described in this article. The target performance of the
drive is based on the requirements for a commercial front-loading washing
machine, with a load capacity of 11 lbs., which
has an inner drum size of 460 mm. The production washing machine uses a
universal motor drive, fed with AC from a
phase-controlled triac. The motor rotates the drum through a belt drive,
and the pulley ratio is 15:1. The aim is to design
the induction motor drive to meet the torque speed needs. The base speed
range is 1:14.5 for a wash speed of 55 r/min
and a spin speed of 800 r/min. Increased spin speeds are desirable,
requiring an extended speed range. Also, a slower
"gentle wash" speed may be used. By applying variable frequency, variable
voltage with slip control these requirements can
be met by a high-speed induction motor operating with a suitable pulley
ratio. The experimental drive comprises a
high-speed three-phase induction motor fed by an inverter.
