Alcoholic discussion - ac versus dc motors
Why is that when you are at one's intellectual worst that the more
complex of discussions occur - solution of the world's problems, etc !!! This particular one revolved round ac and dc motors - covering single phase v. 3 ph induction motors and their relative power /torque capabilities and how they work, which was hard work 45 years after university, but what triggered the whole discussion was how Bosch can claim that a lawnmower with a 36v Li-polymer powered dc motor can have the same capability as a 1700w ac motor. OK 1700w is a comfortable 2hp but single phase induction motors are not too good on torque, and if I remember that is where dc motors score but are modern ones going to match a 1700w ac motor ? Can anyone help or point me at a site on this topic please. Rob |
