Connecting to electricity supply
Wiring for single-speed drive
Motors up to 2.2 kW usually have direct startup,
whereas a star-delta circuit is usual as of 3 kW.
Wiring for two-speed drive with 1:2 ratio
(Dahlander winding)
For example, for 1500/3000 rpm or 750/1500 rpm
Wiring for two-speed drive
(2 separate windings)
For example, for 1000/1500 rpm or 750/1000 rpm
Wiring for three-speed drive
(2 separate windings, 1 is a Dahlander winding)
For fan drives with speeds of 750/1000/1500 rpm or
8/6/4-pole; 750/1500 rpm with Dahlander winding.
Wiring for three-speed drive
(2 separate windings, 1 is a Dahlander winding)
For fan drives with speeds of 500/1000/1500 rpm or
8/6/4-pole; 500/1000 rpm with Dahlander winding.
