Now this isn’t a perpetual motion machine, but it’s darn close. What [lasersaber] has done instead is to make the EZ Spin, an incredibly efficient motor that does nothing. Well, nothing except look ...

There is hardly any field in the world of electro-mechanics that has not found an application for the stepper motor. They are used extensively in the world of model making and as actuators in remote ...

You probably know that if you spin a motor (mechanically) it generates electricity on what would normally be the inputs. This can be a problem when you shut off a spinning motor and is the reason that ...
