The 4 Quadrants are;
1 FORWARD DRIVE
2 REVERSE BRAKING
3 FORWARD BRAKING
4 REVERSE DRIVE
My experience with synchronous motors is in the operation of large rotating mills. In that case, the motors are decoupled from the load by means of an air-clutch, and main power is removed from the rotor and the stator. The motor coasts to a stop. If the motor is operated on a variable speed drive, it could be decelerated to very low speed before removing power.
Give a brief idea of principle of hysteresis motor,application.
Control means, a timer cant control is speed directly, it can control its operation. A times will have NO nd NC contacts. Connect the motor in series with the timer contacts wrt desired operation
A brushed DC motor is internally commuted electric motor design to run from direct current power source. Brushed motor were first commercially application of electric power to driven mechanical load.
No, three phase motors do not actually have neutral line unless you are referring to the motor control centre where a neutral line is required when your control coils and other components are single phase operated
A drive or a motor
The main difference between EDO (Electrically Operated Device) and MDO (Manually Operated Device) in an air circuit breaker is their mode of operation. EDO operates through an electric motor-driven mechanism, while MDO is operated manually by the user. EDO provides automated control and remote operation capabilities, whereas MDO allows for manual operation in case of electrical failures.
what is the function of motor device

The importance of the electric motors is that it provides a motor which can be operated without volatile fuels or harmful exhaust. It provides consistent power which can be operated in nearly any environment.
A synchronous motor is an ac motor that does not run on dc.
Build a small battery-operated vibrator.

If the motor is operated from a three phase three wire distribution system the motor will not need a neutral wire.
The main difference between a MOV (Motor Operated Valve) and a ZV (Zone Valve) lies in their intended applications and functions. MOVs are typically used in industrial settings to control the flow of fluids or gases by using an electric motor to actuate the valve. On the other hand, ZVs are commonly used in HVAC systems to control the flow of water or steam to different zones within a building. Additionally, MOVs are usually larger and more robust, while ZVs are smaller and more compact due to their different purposes and environments of use.
yes.because the direction of motor is same in both half cycles
