Just updating, I've worked out how to calculate the Torque, and the Angular velocity. But to find the angular velocity i need the Back EMF, and I am still unsure as to how i can find this theoretically before i find the angular velocity? Also to find torque i need a value called 'Field density...
I would like to work out the number of coils i need to use in a 3 armature DC brushed motor, using AWG 24 wire, 3A ( can be up to 5 if needed), the magnets being used have B=1.25 T ( id also like to know if a stack of 4 would make 5T? ) The output of the motor must be 25W of mechanical...
Homework Statement
Hi, well my task is to construct a DC motor. With 25w rotational mechanical output power. It cannot draw more then 5A current, and has to have 3 or more poles in rotation. The motor must be brushed/commutated. There is a max of 30v D.C. input. The motor needs to be built and...
