The movement of which subatomic particle causes an electric motor to run?
Eectrons moving in the wire that is why it is called electricity. Electrons moving in a circle around the iron core called the armature produces a magnetic field. This produces a north and south pole. The poles of the armature are attracted to the opposite poles of the magnets, causing the armature to spin. See this website for good diagram of interiofr of motor http://electronics.howstuffworks.com/motor1.htm
What do the neurons of the motor pathway control?
Motor pathway neurons control your motor skills such as walking, running, lifting your arm.
Switching of the poles?
This question doesn't really have enough information. I'll assume that you are talking about a DC circuit where switching of the poles would mean to reverse the polarity of the circuit, ie switching of the poles would mean to switch the positive and negative leads of the circuit. This term is also associated with motors. Switching of the poles in motors is what causes the rotation of the armature. The brushes of the motor induce a current into the armature, as the armature rotates the brushes come in contact with other bars on the armature thus "switching of the poles".
What is base speed?
The base speed of a DC motor is the speed at which it operates while delivering rated torque with rated armature voltage and field current applied.
How does the brain control motor development?
identify aproximately when the brain begins to control the following functions motor development
What is common methods control speed dc motor?
there are two methods i.e armature control method and field control method....
In what two ways can the speed of a dc motor be varied?
speed of a dc motor can be varied by mainly two methods:- 1)field control method 2)armature control method further , field control method can be divided in 3 parts:- 1)field rhestat control method---speed variation is acomplished by means of a variable resistance inserted in series with shunt field 2)reluctance control method---by changing the reluctance of magnetic circuit by choosing right material.. 3) field voltage control method-requires variable field voltage supply. and armature control method can be divided in 3 parts :- 1)armature resistance control---variable resisitance connected in series with armature 2)shunted armature control. 3)armature voltage control. ------------mrityunjay pandey (kiit university ,btech 2nd year)

Is 4 point starter used to start and control the speed of dc shunt motor with armature resistance control?
yes
How do you conduct test on speed control of DC motor using SCR?
Connect the SCR in series with the armature or field and control the firing angle of the SCR which in turns determine the current flowing to the armature or field.
What is Comparison of armature controlled and field controlled DC servo motor?
Difference between field controlled and armature controlled is that field control is open loop and armature current is closed loop.
How can i control the torque of the wiper motor?
there three connections of armature circuit possible in wiper motors. by changing these arrangments, we can control the speed as well as the torque of any wiper motor.
What is armature current?
Armature current is the current flowing in a motor's armature. The "armature" is another name for the coil (or coils) of wire which are on the motor's "rotor", which is the part that rotates inside its stator. (The "stator" is the fixed, non-rotating part of the motor.)
How do you measure the resistance of a motor?
we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance
What are convectional and non convectional methods of speed control of a induction motor?
The flux control method is the convectional and the non-convectional method of speed control of an induction motor.
