Constant Torque Motors (ECM)
For installations where the efficiency of an
electronically commutated brushless DC motor
(ECM) motor is required, but the features of a
constant airflow motor are not required, the SV
series is offered with a constant torque ECM motor
option. These motors feature up to 90% thermal
efficiency combined with a flatter fan curve than a
PSC motor and simple operation. These motors
are provided with 5 speed taps to allow for a wide
range of air flow and external static options. To
change a speed tap follow the instructions below:
1. Disconnect power to the heat pump.
2. Remove the blower access panel.
3. Remove the speed tap wire from the terminal it
is currently connected to and connect it to the
terminal desired.
Refer to the constant torque motor performance
tables for heat pump blower performance with the
constant torque motor option.
