check the brushes
if you are getting dc out of the drive and the motor doesnt start
the motor should also have full field to start
with an extreme overload even a permanent magnet can be discharged or reversed
this is assuming the pwm drive is ok
no and maybe it not connected to your car motor and it motor.

If the motor terminal has six terminals in the terminal box, then it can be connected either in delta or star. If there are only 3 terminal wires then the motor can not be connected in star.(it means that the motor is designed to be connected in delta only)
sir iam doing project in speed contol of induction motor using spce vector modulation please give me suggession sir iam doing project in speed contol of induction motor using spce vector modulation please give me suggession
the motor is 2
It depends on the construction of the motor. If the field winding is connected in series with the armaturewinding, the motor is like a universal motor and will probably operate normally. If the field winding is connected in parallel with the armature, the motor will not run, but will draw current, make noise and get hot.
The solution to this problem is to get the same size motor in HP at the correct voltage. This way the motor can correctly drive the connected full load without tripping the motor protection.
break is connected with parallel to motor winding if the brake is d.c. is supply it must be connected with rectifier unit,when motor in ideal position the brake holds the shaft which is connected with gear and when motor starts the break coil will energise and motor shat became free and motor will run like this brake work
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
The value and kind of resistors, connected in series or paralell, type of dc motor, what is the purpose, etc.
Generally a motor drives some equipment, it could be a fan, or a pump, connected to motor's shaft. The speed of the motor when no equipment is connected to its shaft is known as no load speed.
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
