R-Winding-Smoother, Quieter Motors
Most step motor users are familiar with Series and Parallel connections; now, the patented R-Winding (U.S. Patent No. 6,969,930) has been created to reduce noise and vibration for lower-torque applications. Step motors typically run with a driver that either half steps or full steps. For example

Fuel cells' long and winding road
reformer to electric motor, will be twice as efficient as today's gas-powered cars, thereby offsetting methanol's lower energy content per gallon. Manufacturing headaches. Fuel cells have to be collected into a fuel stack, like batteries in a series, to generate enough voltage. They will need

T-connect for steppers
the combined resistance of each winding lowers overall current, it also combines the inductance of each winding. High inductance prevents operation at mid to high speeds. The T-Connection also lowers current consumption by wiring two opposing windings in series. However, the mutual inductance of the two
