Depending on the voltage necessary for the motor’s operation, you can choose a low or high voltage controller. A switching regulator works well for controllers with a wide operating voltage range.
A current carrying wire in the presence of a magnetic field experiences a mechanical force that acts in a particular direction. To determine the focus of this force, Sir John Ambrose Fleming established a simple way that uses one’s left hand to visualize the relationship between the flow of current, the direction of the magnetic field, and the direction of the force. This simple yet highly effective technique became known as the Fleming Left-hand rule.
An easy and instant way to do this is to replace the R2 resistor with a potentiometer, and additionally add two diodes in the circuit.
AC motors are driven by alternating current, and stepper motors are driven by pulses of electric power. DC motors on the other hand are powered by direct current, and have the following features.
type DC Motors (permanent magnet types), our range does not apply to brushless which uses a completely different method to control motor speed than a brushed motor does!
This page will show step by step the relationship between speed, torque and drive voltage of a DC motor, and how to control it.

The direction of the motor’s spin can be changed by swapping the wires connected on either terminal of the DC motor. If the motor runs by itself and not when connected to the resistor, the value of the resistor is too high for the motor and a lower resistance is needed.
If this causes many problems, a switch may be installed between these components to shut off the circuit when needed. Once both ends of the wire are connected, the circuit will be ready.
All direct-current motors must have two core elements: a stator and a rotor (armature), although critical functions can be performed by other components as well. A brushed DC motor comprises the following units:
If we start to reduce the maximum voltage at which the motor rotates at maximum speed, the speed of the motor also starts to reduce. In this way these enable pins are helpful to control the speed of the DC motor.
By decreasing the flux produced by the field winding, the speed can be increased and vice versa. Hence the name flux control method or field control method.
Now look at Mode 4. Here we have current moving from W to V; this is the just the reverse of Mode 1. With a brushed DC motor, this type of current reversal would be achieved using brushes and commutator.
So far, however, we have not looked at another important feature of these motors: their positional sensors. Because BLDC motor control must be coordinated with the rotor (magnet) position, these motors typically also include sensors to detect this position.
