The MOTOR SPEED CONTROLLER controls the speed of DC motors or acts as a light dimmer.
Powering an electric motor directly from a battery or power supply will only allow a motor to function at a constant speed. The speed of the motor is directly related to the voltage of the battery or power supply. The MOTOR SPEED CONTROLLER circuit allows the user to adjust the speed of a motor from anywhere between a stopped state up to full speed. The same system can be used as a light dimmer for a 6Volt bulb.
The circuit uses Pulse Width Modulation (PWM) to control the speed of a motor. The way Pulse Width Modulation is used to control motor speed is explained later in this Teaching Unit. This circuit will work with any motor sold by Scorpio Technology. This kit does not contain a motor nor a light bulb.
HINT: When paired with the GENERATOR OUTPUT MONITOR (Code: GOM) and a motor (e.g. MOT17) this is ideal for demonstrating power generation.
