What are the two types of motor control?
Different Types of Motor Controller Motor control devices are designed to be controlled in a manual, automatic, or remote manner. They can be used for starting or stopping a motor attached to a machine as well as serve several other purposes.
What controls the motor speed?
Thus, the speed of a DC motor can be controlled in three ways: By varying the supply voltage. By varying the flux, and by varying the current through the field winding. By varying the armature voltage, and by varying the armature resistance.
What is meant by motor current?
The current drawn by a motor at its full load, calculated using formula is known as the rated current. Motor windings are designed to carry the rated current during normal operations and slightly higher than it for shorter duration.
Can a low current signal be used to control a high current motor?
The convenience of an H-bridge is that a low current digital signal can be used to control a high current motor (or other device). Full H-bridge circuits capable of a few Amps can be purchased in convenient IC packages (see PWM and H-bridge chips ).
Can a microcontroller be used for a high current motor?
In this way two things can be achieved: 1. Running our high current motor itself. 2. Isolating the circuit, thus preventing any shocks. Now any microcontroller can be used to switch these relay. We will be using arduino UNO here.
How to make a high current motor circuit?
Contacts must be rated to handle the high current motor specifications 4. BATTERY (12v) : to supply power to motor. 5. TWO PUSHBUTTONS: to give inputs to arduino (i.e. when pressed and when not pressed) 6. TWO 10K RESISTORS: for debouncing (explained below) 7. CONNECTING WIRES: for making connections.
