No. In a "regular" DC motor, the permanent magnets form the stator, and the brushes and commutator are used to get the DC to the rotor windings. In a brushless DC motor, the magnet is the rotor, and the stator is a group of coils arranged in a circle to form the stator. The electronic controller drives the individual coils in the stator. There isn't a good way to drive them without an electronic controller. A link is provided to the Wikipedia article on the brushless DC motor (BLDC). At least surf on over and check out the pics. The ones showing motors that have been taken apart are particularly helpful.
1. A squirrel cage Induction motor is lesser costlier than electrical drive because of using coverters and control circuits . 2. Technology for dc drives is improved compared to ac drive 3. It is not reliable
When torque increases in a BLDC motor, the speed decreases. This is because as more torque is applied, the motor has to work harder to maintain the same speed. The relationship between torque and speed is inversely proportional in BLDC motors.
BLDC motors
A brush-less DC motor (BLDC)
stepper motor No. it is not a stepper. It is a Brushless DC (BLDC) motor. See related link for more information on this motor.
Among one difference noted, the typical brushless motor has permanent magnets, has a higher efficiency and a lower susceptibility of the commutator assembly to mechanical wear.
It is possible to run a DC motor on a 3-phase supply using a full-wave rectifier if the voltage is right.

IN BLDC OPERATING MOTORS i.e. FAN IN THE CPU,ADC
Transmitter and receiver(4ch+), ESC, Motor, battery, servos. Thats about it for the electronics
An electric car power train consists of the battery and it's control and charging electronics, the electronic inverter and it's computer and instrument panel,the electric motor which is most likely a Permanent Magnet Electrinically Commuteted Motor (PMEC_motor) also called a BLDC motor though the two are different. There is also a gearbox and differential.

This is just to give you an idea on how to get started not the complete instruction. To have better understanding check out how BLDC motor works in youtube.Then you find below something relevant. To make a motor(to learn how it works) you need to create a stator which on excitation creates a rotating magnetic field. It must spatially create a field as if north and south poles are rotating at some speed. To do this, you need make simple electromagnets (four) arranged 90 deg from one another. The electromagnets placed in opposite are connected in series. So now you have four wires comming out(2 phases) .Now phases are energized one by one with additional electonic circuitry. Stator is supplied with DC with aid of power semiconductor devices. In the rotor part can have permanent magnet which will try to align itself such that north and south poles of the rotor(magnet) will try to align with rotating field. The rotor is pivoted at the center such that it is surrounded by stator poles. By exciting the stator ,the rotor will eventually try to align itself and rotate.
