(1) make sure electromotor moving environment is favorable (2) make sure electromotor temperature rise does not exceed a level
(3) change the electromotor with big loss
(4) the starting number that limits electromotor
(5) the empty runni...
At present more commonly used AC motor has two kinds: 1, three-phase asynchronous electromotor. 2, single-phase AC motor. The first kind multi-purpose go up in industry, and the 2nd kind multi-purpose go up in civil electric equipmen...
Of electromotor lubricant
The breed of electromotor and norms size are numerous, the lubricant of general electromotor is chosen depend on bearing type, revolution and temperature, bear.
Small-sized electromotor is commonly used...
1 those who understand electric machinery principle ask what how change electric machinery of alternating current fan into ~ ~ ~ to change direction
My electric machinery wiring is, red, green, yellow, now red yellow receive capacitor,...
The working principle of AC motor
At present more commonly used AC motor has two kinds: 1, three-phase asynchronous electromotor. 2, single-phase AC motor. The first kind multi-purpose go up in industry, and the 2nd kind multi-pu...
Concept: What dc motive points to is to use direct current source (be like: Dry cell, accumulator) electromotor; What AC motor points to is to use communication (be like: Domestic circuit, alternator) the electromotor of power source...
Cover pole electric machinery
Electromotor of cover pole type is the simplest kind in one-way AC motor, use normally basket model aluminous rotor of inclined chamfer casting. It according to stator appearance structure different, divide ag...
The pace already was become into electromotor except the 3rd kind of electromotor beyond dc motive and AC motor. Traditional electromotor changes unit as Electromechanical energy, the effect that there is a key in electrification proc...
