About 5-Speed ECM Constant
Torque Motors
The 5-speed ECM is a ‘Constant Torque’ ECM motor and delivers
air fl ow similar to a PSC but operates as effi ciently as a variable
speed ECM motor. Because it is an ECM motor, the 5-speed
ECM can ramp slowly up or down like the variable speed ECM
motor. There are 5 possible speed taps available on the 5-speed
ECM motor with #1 being the lowest airfl ow and #5 being the
highest airfl ow. These speed selections are preset at the time of
manufacture and are easily changed in the fi eld if necessary.
If more than one tap are energized at the same time, built in
logic gives precedence to the highest tap number and allows
air fl ow to change with G, Y1, Y2 and W signals. Each of those
5 speeds has a specifi c ‘Torque’ value programmed into the
motor for each speed selection. As static pressure increases,
airfl ow decreases resulting in less torque on the rotor. The
motor responds only to changes in torque and adjusts its
speed accordingly.
The 5-speed ECM motor is powered by line voltage but the
motor speed is energized by 24VAC.
5-Speed ECM Benefi ts:
- High effi ciency
- Soft start
- 5 speeds with up to 4 speeds on-line
- Built in logic allows air fl ow to change with G, Y1, Y2 and
W signals
- Super effi cient low airfl ow continuous blower setting (G)
