What else can I help you with?
Why will the rotor of a wound-rotor motor not turn if the rotor circuit is left open with no resistance connected to it?
Because there is no current flowing in the rotor, and thus there is no magnetic field in the rotor, and thus there is no torque between the rotor and the field.
What is a helicopter blade called?
the blade is called rotor bladesThe rotor blades on top are called Main Rotor Blades, because they are the main source of lift for the helicopter. The smaller rotor blades on the tail are called Tail Rotor Blades.
How do you measure the thickness of a rotor?
What is a rotor?
What is the rotor head for?
The rotor head changes the angle of incidence of the rotor blades as they rotate.
What type of rotor is found in a universal motor?
Wound rotor and squirrel-cage rotor
Why does a typical small helicopter with a single rotor have a second small rotor on its tail?
The small rotor on the tail, called the tail rotor, counteracts the torque produced by the main rotor of the helicopter. Without the tail rotor, the helicopter would spin uncontrollably in the opposite direction of the main rotor. The tail rotor helps maintain the helicopter's balance and heading.
How do you resurface a rotor?
The rotor will have to be removed from the car. It can be resurfaced by mounting it on a special machine that slowly removes metal from the rotor until the rotor is smooth.

Can you replace just one rotor?

What happens to the rotor speed and rotor current when the mechanical load on an induction motor increases?
rotor speed will decrease....the rotor current wil increase.....

What is palindrome for part of a machine that turns or rotates?
The word rotor is used to refer to a rotating part of a machine. It is also a palindrome.
