What operating condition is most likely to overheat a motor?
When dc motor run full torque at low speed. Armature current is high and field current is set to max to get the torque. When motor is field weaken then temperature decrease at same cooling air flow
Why a dc series motor should never run at no load condition?
if you run the unloaded motor at max rpm the centrifugal forces will cause the motor to be totally destroyed so it is advisable to not to run it at max rpm it should be okay to run it till 50% of max rpm without loading it
Which parameters speed of DC shunt motor depend?
base speed is the speed with full voltage on the shunt this speed is mostly from the number of poles , single pole fastest max speed is when you weaken the shunt the limit is the amount of power the armature can take and thing like bearings an strength of the reinforcement of the windings
What is the difference between max torque and breakdown torque of a electric motor?
Max torque and breakdown toarque are the same...,.the point at which a motor will stop/stall.
Which motor rotate above synchronous speed?
An induction motor rotating at higher than synchronous speed would be generating power, thus would be a generator. No motor operating as a motor runs above synchronous speed.
How many 2838 Lego motor rotates per minute?
A 2838 Lego motor has a max speed of 4100 rpm.
No blower motor speed 123 only max on Nissan Maxima 1997?
change the blower motor resistor. done deal.
When the posted speed limit is 70 mph what is the max speed?
The posted speed limit is the max speed.
What operating condition is most likely to overheat a motor?
When dc motor run full torque at low speed. Armature current is high and field current is set to max to get the torque. When motor is field weaken then temperature decrease at same cooling air flow
What was the max speed of a Spitfire?
The max speed of the final Spitfires was about 460 mph.
How much speed does Indian train have?
A goods carrier Max speed is 80/ph Express Speed Max : 120 /ph Super fast Speed Max: 160/ph.
1999 Ford Ranger Air Conditioning fan speed switch only blows air on max ac Is this a switch or fan motor problem?
If you are saying the blower motor only works on the high speed setting, then the problem is a bad HVAC Resistor Pack.
What is the max speed on a 49.9 cc moped?
the max speed is 90 km/h
How many horses does the h22a engine have?
190hp
How much horsepower does a 1981 Corvette have?
190hp
What is the speed of DC series motor at no load?
No load speed is the speed that the motor run when it has no load, i.e., the motor is separated from the engine, that speed is than greater than the rated speed, because the rated speed is the speed whwn the motor are linked to the load and it is the full load.
Why is a synchronous speed motor considered a constant speed motor?
synchronous motor is a constant speed motor because it will only run at a synchronous speed or not at all.the speed can be changed by changiing the frequency only ns=120f/p
