What motor is NOT suitable for use as a DC machine?
In DC series motor, field and armature are in series. so we use only two points. They are line and armature. therefore we use two point starter.
Because it has three terminals L , F and A L - Line (connected to Supply) F - Field (connected to field of dc motor) A - Armature (connected to armature of DC motor) that's y it is called 3 point starter :)
Examples of DC electric motors are the starter in your car and the motor in a DC controlled elevator, to name just two.
A two-point starter is used to control the starting of electrical machines, such as DC motors. It helps limit the initial current surge during the starting process by gradually increasing the voltage applied to the motor through the use of resistance. This protects the motor's windings and prevents damage due to high inrush current.
shunt type dc motor use in train fans
That depends on the drive system:Toyota Prius hybrids use AC from an inverter to power AC drive motors.Honda hybrids use DC to power DC drive motors.All electric vehicles may use either AC from an inverter or DC to power drive motors, depending on the type of motor.Ordinary gasoline vehicles use low voltage DC to power a starter motor and generate spark for the cylinders.Ordinary diesel vehicles use low voltage DC ONLY during startup, to heat glow plugs and to power a starter motor.
armature
no you can't use dc motor to power hydro turbine ?
