Because the slip angle between magnetic fields decreases as the rotor comes up to speed.
star delta motors start as a Y for 3 phase so the windings that normally see 480 volts see 277V a relay switches to delta then it runs as a normal delta motor the reduces the starting current by about 60% for 3 phase
for protection from initial currents and short circuit,overload currentsFurther ExplanationWhen a motor is stationary, the only opposition to current flow is the resistance of its windings. When the motor starts to turn, it generates a back emf. So, on starting, the current is high, and it reduces in value as the machine runs up to speed. With larger motors the starting current could overheat and damage the windings, so it is necessary to restrict the value of the starting current using a 'starter'.
A DC motor is an electric motor that runs on direct current (DC) electricity. A DC motor is designed to run on DC electric power. Two examples of pure DC designs are Michael Faraday's homopolar motor (which is uncommon), and the ball bearing motor, which is (so far) a novelty. By far the most common DC motor types are the brushed and brushless types, which use internal and external commutation respectively to reverse the current in the windings in synchronism with rotation.
It is overloaded. take the motor loose and see if it runs normally if its on a machine that used to work check bearings misalignment bent shafts
The FLA of a motor is the amperage that the motor operates at. So to answer the question, 100%.
This configuration is used to reduce the starting current. Utility companies do not like large motor loads starting across the line. It dips the voltage level of the line. By reducing the starting current to a lower level also reduces the voltage dip in the supply lines.

Maximum current is defined by the rated KW of the device, say Motor. The motor may not run at its maximum rated capacity all the time. Nominal current is drawn when motor runs at nominal load.
it really depends on the motor specs but yes it can because the muffler not only reduces engine noise it also provides enough back pressure for your vehicle to runs more efficient
When a motor is stationary, it is not generating a back-mmf which would otherwise act to oppose the applied voltage and, thus, reduce the supply current. However, as the motor runs up to speed, it generates an increasing back-emf, and the supply current falls.

The frequency of the applied voltage is constant.
when the motor runs more than rated speed it produces leading current and results act as a generator. (or) the motor act as generator when it produces more back e.m.f
It depends on what it runs on. A motor runs on electricity and an engine runs on fossil fuels. It depends on what it runs on. A motor runs on electricity and an engine runs on fossil fuels.
