Increasing the number of wire turnsDescreasing the strenght of the fixed side magnetsMaking more splits in the commutatorChanging to a power supply with more electical output.Help please!
If it is an AC motor, the speed will be set by the frequency divided by the mumber of pair of poles. One pair of poles will give you the highest speed, equal to the network frequency. Most AC motors are two pairs of poles. You can also use a variable frequency drive. If it is a DC motor, it will spin faster if you reduce the shunt field current/voltage. I.e., descreasing the strenght of the fixed side magnets . .
Increasing the number of wire turns but you can't do that for an existing motor.
