How A Motor Controller Works
An electric motor is a power-driven electrical device which converts electrical power to mechanical power through the interaction of two magnets. Most electric motors work in a parallel fashion between the primary magnet’s field and the current through a wire winding, which in turn creates a direct current. Alternating current is used for motors that are designed to run on a battery rather than using alternating magnetic fields.
As electricity is produced from a motor it is sent from the generator into a motor controller where it is transformed into electrical power for the vehicle. A motor controller is also known as the speed controller and contains a number of settings that determine how the various components of the electric motor are used together to produce electric power. The speed controller has various settings depending on whether it is in continuous or emergency mode. Emergency mode allows a motor to be switched off while in continuous mode the motor is set at a particular speed and then switched off automatically when the speed reaches the set point.
The main part of a motor consists of its rotor, hub and shaft and the main components of a motor are brushes, wires and springs. The brushes are made up of copper strips of different sizes with a flat copper wire attached to one end of each strip. The copper wire helps in creating the rotation of the rotor, which in turn provides the motive force. The brushes provide friction to prevent wear and tear. The shaft, on the other hand, is the part that rotates and converts the power into kinetic energy. The shaft is connected to the center of the engine to reduce friction between the rotor and shaft.
The speed controller allows the car to go faster without decelerating so it must be used in conjunction with an appropriate speed sensing system. The speed sensing system is an electronic circuit that is linked to an electronic controller board that controls the speed of the motor. The speed sensing system is responsible for detecting a change in speed of the engine as well as controlling it with the help of a computer. It monitors the engine’s RPM and uses the software in the controller board to send an electronic signal to the speed sensing circuit when the RPM changes.
The size and weight of the vehicle determines the amount of power required for it to move and if a motor is needed for the car to accelerate and travel faster. If a large engine is installed in a small car this will cause a great strain on the drivetrain and can result in increased fuel consumption and wear and tear.
There are several types of speed controllers available for a car and the type will depend on the engine the car has. A number of electronic parts are required to work together to provide control for the car’s motor so it is important to know what type of motor controller is required for the vehicle. When selecting the correct one for a particular model of car it is advisable to check that all necessary parts are available and have been used in a car before buying one.
