What kind of AC load uses the energy needed to magnetize a motor or a transformer winding?
inductive load
What is a split phase motor with relay and capacitor called?
A capacitor start motor is a split phase motor that uses a capacitor in series with the start winding to cause a greater phase shift, resulting in greater starting torque. It uses a centrifugal switch to switch out the start winding and capacitor once the motor is up to speed. I assume this switch is what you're referring to as a "relay".
Differences of induction motors and synchronous motors?
An induction motor is a type of electric motor. It uses alternating current (AC) electricity and induces (hence the name) a current in the rotating part to make it move. You might call it a rotating transformer. A hydraulic motor is powered by a fluid. Typically this might be an oil, The oil forces round some gears or vanes to make the motor shaft turn. A hydraulic motor requires an external supply of pressurised fluid, e.g. oil. Large earthmoving equipment or diggers use hydraulic power as it is compact and powerful for its size.
How do you connect a single phase capacitor start induction motor forward?
This is for a single voltage motor. If you consider the forward rotation as counter clockwise (CCW) when looking at the motor from the end opposite the drive end, then the connections will be, L1 - terminals 1 and 8, L2 - terminals 4 and 5. To reverse the rotation (CW), then the connections will be, L1 - terminals 1 and 5, L2 - 4 and 8.
What is ment by restraining coil?
straining coils are winding that we uses to prevent the fault operation of relay
What kind of AC load uses the energy needed to magnetize a motor or a transformer winding?
inductive load
Working principle of synchronus motor?
A synchronous motor is a three phase motor, which uses a magnetic field created by permanent magnets or a DC electromagnet on the rotor (usually). The stator windings have 3 phase voltages applied, and coupled with the DC field, create a rotating magnetic field that drives the motor at synchronous speed.

How do you connect capacitor to a capacitor start motor?
A start capacitor is wired in series with the motor's start winding via a centrifugal start switch. The switch disconnects the capacitor and start winding once the motor has reached a pre-determined minimum speed. The motor then continues to run on its main field winding. A different design uses a "start-and-run" capacitor which remains in circuit whilst the motor is running.
Why does modern hybrids use ac synchronous motor instead of dc series motors?
Toyota uses AC motors, Honda uses DC motors. It varies with design goals.
Might a synchoronous motor equally well be called a synchoronous inductor?
No. An inductor by definition is a passive component that stores electrical energy in an magnetic field. It does not use real power (in any serious amount). A synchronous motor is not passive, and uses real power.

What is easier to climb winding staircase or steep staircase why?
a winding because you body must twid and change direction and it uses energy :)
What transmission synchronization methods uses the cyclic redundancy check method for error checking?
Synchronous
What are the uses for a coil winding machine?
winding machine is used to wind the string, wire, cable, thread, rope, etc onto a spool or bobbin. They are of various types from simple winding machines to complex programmable winding machines like CNC winding machines. Mostly winding machines are used in textile, and paper industries, to quickly wrap a large amount of string or paper onto a spool. These winding machines are used by small to large businesses according to the winding needs.
Why SONET is called synchronous network?
Because SONET/SDH uses "synchronous TDM multiplexer" to multiplexe signals from multiple electrical sources . All clocks in the system are locked to a master clock.
