Re: Additional field coils around motors

the effect of increasing the strength of the field is twofold:

1. you will have more torque for a given voltage
2. your top speed will be lower

the reason for #2 is the stronger field will generate a larger counter-EMF, the back voltage that determines the motor top speed.
