What is an industrial DC motor?
A DC motor is a machine that converts direct current electrical energy into mechanical energy. When electric current is applied to the windings in the motor, it is based on the principle of moving with the effect of the magnetic force formed in the opposite direction to the permanent magnets inside the motor.
Why is a starting device needed to operate direct current shunt machines?
In these machines, the resistance value of both the armature windings and the excitation windings must be very low, since the total operating current passes through the excitation windings. The current drawn by serial machines, especially during development, is very high and therefore must be limited through a starting device.
What is the rotating part of DC motors called?
The number of poles varies according to the speed and power of the machine. The rotor is the part that carries the conductors and in which voltage is induced. The rotating part of DC motors is called rotor. Mechanical energy is taken from the rotor shaft.
How many volts does the DC motor run?
Voltage: Small DC motors can be found with voltage values ranging from 1.5 V to 48 V.
What does the engine do?
The engine is a machine that converts an energy form (electricity, chemical energy, gasoline, thinner, LPG, etc.) into mechanical energy. Power machines used in vehicles and generators are heat engines.
What is the function of the commutator in a DC motor?
Similarly, in the dc motor commutator converts input direct current into alternating and given to the armature thus producing torque in the engine. Here, to run a dc machine either in the case of motor or generator it is essential to have current to be alternating which is done through process commutation by the commutator.
What is a commutator on a coil?Simply put, the commutator turns the coils on and off to control which direction the electromagnetic fields are pointing. On one side of the coil, the electricity should always flow “away,” and on the other side, electricity should always flow “towards.”
What is a commutator in a torque converter?Commutation is the process of switching the field in the armature windings to produce constant torque in one direction, and the commutator is a device connected to the armature, which enables this switching of current. The lever arm for the torque produced on the armature varies with the angle of the coil (cos α).
