What supplies a dc motor is not current, but voltage. Current is what flows in the circuit formed by the dc motor and for the charge. That current varies according to the resistance of the circuit.

What is the electric current supplied to most homes celled?

The electric current supplied to most homes is alternating current (AC).


How veriable frequency drives works?

Variable frequency drives (VFDs) control the speed and torque of an electric motor by adjusting the frequency and voltage of the power supplied to the motor. They convert incoming AC power to DC, then back to AC at a variable frequency and voltage. This allows for precise control over the motor's speed and power consumption, leading to energy efficiency and optimized motor performance.


How do you calculate how much electricity a DC motor will generate?

A DC motor will generate electricity, if used in reverse. IE, rotate it and electricity will be generated. The voltage will be dependant on the speed of rotation. The capacity (Amperage) will depend on the size of the windings and diameter of copper wire involved. Limitation to power and speed will also be limited by the construction of the commutator. All these variables are difficult to predict and unlikely a formula is available. You will need empirical means and careful testing, especially as the motor was not intended to be used in this way.


What is difference between d.c genrator and motor?

GENERATOR:converts mechanical energy to electrical energy.It works on flemings right hand rule.It works on the princple that an EMF is induced when a changing magnetic field links with the conductor. This emf is directly proportional to the rate of change of magnetic field linking the conductor.MOTOR:converts electrical energy to mechanical energy.works on flemings left hand rule.It works on the princple that a mechanical force is experienced by the current carrying conductor when placed in magnetic field.

Does the alternating current supplied to the armature winding of a DC motor gets converted to dc by a commutator before it flows through the armature coil of the DC motor?

The commutator is a rotating switch, which reverse the polarity of the generated voltage every half-cycle. So it acts to rectify the output voltage.

Why DC motor current ripple?

The induction of a DC motor while rotation lead to a non continuid current. This AC part of the DC csupply current is called ripple current. You can measure this and see if the motor is moving and also you can count the ripple per second and have the motor speed "RMS".


What is DC motor?

A DC motor is an electric motor that runs on direct current (DC) electricity. A DC motor is designed to run on DC electric power. Two examples of pure DC designs are Michael Faraday's homopolar motor (which is uncommon), and the ball bearing motor, which is (so far) a novelty. By far the most common DC motor types are the brushed and brushless types, which use internal and external commutation respectively to reverse the current in the windings in synchronism with rotation.
