Why need a time elapse between turn off and turn on to a three phase induction motor and what is the that minimum time?
Rotor current is is highest when an induction motor is starting, due to the high slip angle. The Squirrel cage rotor winding heats up and expands. The rotor must be cooled before it can withstand another start. The stator winding heats up also, but typically the rotor is the week link. The rotor cools faster when it is running. Plugging a motor (short run followed by another short run) is the worst. Check with the manufacturer for the proper wait time.
What are Types of cooling in transformer?
Air cooled water cooled oil cooled Totally enclosed fan cooled Refrigerant cooled
Is a Honda goldwing 1100 oil cooled or water cooled?
Water cooled.
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.
Is Air cooled vs water cooled pocket bikes?
water cooled is better
How do you measure the thickness of a rotor?
What is a rotor?
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.
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
Will a Yamaha banshee engine fit on a 1973 Yamaha RD 350 frame with out fabrication?
Yes it will, the banshee engine is just a water cooled version of an RD engine. The bottom ends are identical except for the rotor end of the crankshaft is slightly longer. You will probably want to get the banshee wiring harness also. (Also a RD350LC was built where the LC at the end stood for Liquid Cooled).
Which side do you approach a helicopter with a patient?
You should make eye contact with the pilot and follow his signals. He may not want you to approach at all until he shuts down. Due to the way helicopter engines are cooled, this may take a couple minutes. At any rate, you should NEVER approach a running helicopter from the rear. The tail rotor is every bit as deadly as the main rotor.
