You can make engine power regulators up to 2 kW yourself. This will require available parts that are sold on any radio market. Assembly of such a device is quite simple. Using the circuit, you can control a powerful transformer, heating devices, etc.

Regulator manufacturing process
To assemble the regulator, we take any rigid base, for example an aluminum radiator. We screw the BTA41-600B triac onto it using a dielectric spacer and a screw with a non-conducting bushing.
We glue a variable resistor to the right with a slight indentation. Then we tin the contacts of the resistor and triac. Now we take the DB3 dinistor. We solder it to the right leg of the triac and two contacts of the variable resistor, as shown in the photo.
We solder a 10 kOhm resistor between the central leg of the triac and the right variable transistor. Now let's take the capacitor.It must be soldered to the dinistor leg on the side of the variable transistor. We connect the second end of the capacitor through a wire extension to the first contact of the triac.
We connect one wire of the cable with a wire to the same contact of the triac. We solder its second end to the load. It could be a light bulb or an electric motor. Then we connect the remaining wire from the load to the central leg of the triac.
When an incandescent light bulb is connected to this circuit, the device works as a dimmer, allowing you to adjust the brightness.
If we connect an electric motor with a power of up to 2 kW, we get a speed controller.
In general, the device is universal, which can even regulate the voltage on the transformer.
