Permanent Split Capacitor Motors

Permanent split capacitor motors may require an external capacitor to be wired with the motor connections. Mechatronics motorized impellers include the required capacitor with each motor.

Tachometer Output

Some Mechatronics AC Motorized Impellers are available with tachometer output for fan performance monitoring.

This requires AC voltage to power the fan motor and separate DC voltage to power the signal circuit. The signal output wires do not have to be connected for the fan to operate.

AC fans with a signal output option will have 3 additional lead wires:

The AC fan signal output is open collector. The application must include a pull up resistor across a DC power source in order to provide voltage on the output. Reference above diagram

The output is one pulse per revolution and is a square wave output

AC Motorized Impeller Mounting Options

Mechatronics offers the standard motorized impeller package as well as a unique configuration which combines the impeller and inlet ring in one complete package.

Typical Standard Motorized Impeller Installations

Standard motorized impeller integration requires an inlet ring to block the exhaust air from re-entering the air intake. For optimal performance, the inlet ring must be mounted to an adjacent surface aligning it with the impeller intake.

Mechatronics integrated inlet ring option eliminates the need for an additional adjacent surface for an inlet ring. Simply mount the device and power it up. This simplifies integration as well as reduces your assembly labor time.
