Multiple speed motors
The most popular is the Dahlander motor (3-phase) that allows you to run at two different speeds: full speed and half speed.(see picture)
In 1-phase or other 3-phase cases than above, it is possible to wind two motors in one. In current production we have for instance a 1500-1000 r.p.m. symmetrical motor. (see picture)
Care should be taken about starting torque, service, etc... please contact us.
Do not confuse with 50/60 Hz motors who are suitable for both 50 and 60 Hz mains : their speed are set by the mains.
