What is the difference between a thermal motor protector and current-type motor protector?
thermal motor protector is temperature; current type is current.
What is the effect of field current on dc motor?
The field current of a dc motor provides the magnetic field that allows the motor to develop a torque when current flows through the armature..
What allows the current to enter the electronromagnet in an electric motor?
The resistor allows current to enter the electromagnet in an electric motor. The resistor regulates the amount of current that enters the electric motor.
When does a motor draw current more than its rated current?
This is a good indication that the motor is being overloaded. If the motor load is belt driven, remove the belt and then check the motor amps. If it goes back to normal FLA then there is a problem with the driven load. If the motor amperage stays high check the motor bearings for the problem.
How do you calculate voltage drop for starting motor current and how to get the starting pf?

What is the difference between a thermal motor protector and current-type motor protector?
thermal motor protector is temperature; current type is current.
Why current is supplied to DC motor?
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 Full load motor current of a 75KW motor?
Full load starting current is typically in the region of 5or 6 times the full load motor current;.
How many percent will be the starting current for motor?
Motor starting current is typically 5-7 times the rated current of the motor. (For three phase induction motors)
What is the effect of field current on dc motor?
The field current of a dc motor provides the magnetic field that allows the motor to develop a torque when current flows through the armature..
What allows the current to enter the electronromagnet in an electric motor?
The resistor allows current to enter the electromagnet in an electric motor. The resistor regulates the amount of current that enters the electric motor.
What is emf induced in a motor's coil that tends to reduce the current in the coil of the motor?
BACK emf induced in a motor's coil that tends to reduce the current in the coil of the motor. The answer should be 'back'.
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 the current in star connection?
If a motor is connected in star, the current in the motor winding will be equivalent to the line current. If the motor is connected in delta, the current will be 1/sqrt(3) of the line current. If three phase CTs are connected in Delta, their secondary current will be sqrt(3) higher than the CT ratio implies by the line current.
When does a motor draw current more than its rated current?
This is a good indication that the motor is being overloaded. If the motor load is belt driven, remove the belt and then check the motor amps. If it goes back to normal FLA then there is a problem with the driven load. If the motor amperage stays high check the motor bearings for the problem.

Is galvanometer generator alternating current or direct current needed to operate an electric motor?
That depends if it is an ac or dc motor.
