There are three basic types of small induction motors: split-phase single-phase, shaded-pole single-phase, and polyphase. In two-pole single-phase motors, the torque goes to zero at 100% slip (zero speed), so these require alterations to the stator such as shaded-poles to provide starting torque. A single phase induction motor requires separate ...
At ports 2 and 3 the signal arrives in phase and adds whereas at port 4 it is out of phase and cancels. Ports 2 and 3 are in phase with each other, hence this is an example of a 0° hybrid. Figure 12 shows a planar implementation but this design can also be implemented in coax or waveguide.

700 horsepower Brown-Boveri-Déri repulsion motor with 10 poles to be used with 12 kV, 16 2/3 Hz single phase current. Two of these motors were used in the French electric locomotive Midi E3301. A repulsion motor is a type of electric motor which runs on alternating current (AC).
DAF cars had the image of being slow. The company tried to change this image with entries in rallies and races, such as their entry in the London–Sydney Marathon. They were pioneers with continuously variable automatic transmission called Variomatic. A DAF car was used in Albie Mangle's "World Safari" movie of 1977. [17]
