Can I control multiple motors with one fan speed controller?

Motor and fan related questions
Yes, that is possible.

If doing so, make sure that:
- All connected motors are identical.
- The fan speed controller is selected, based on the total motor current required, by adding together the rated current of all the connected motors. The selected fan speed controller must have a maximum current rating that is equal or higher than this sum.
- Each motor is protected by an individual thermal overload.
- The motors remain permanently connected to the fan speed controller and are not individually started or stopped whilst the fan speed controller is enabled.
- When using a frequency inverter: operate in V/F Mode only and apply an output filter.

In the scenario of one fan speed controller per motor, each motor can be controlled separately and run at a different speed. This is not the case when multiple motors are controlled via one fan speed controller. Secondly, running multiple motors from one fan speed controller creates a single point of failure.
