1. In an electronically commutated motor having three phase windings, a commutating and control circuit comprising direct current supply means, commutating switching means for selectively connecting said ... Various types of motors with electronic commutation applied directly to the phase windings are already known.

This lesson presents dc armature terminology and identification, bar-to-bar testing procedures, and growler testing procedures. An important point to remember in this lesson is that there are only two types of armature windings, lap and wave.

1. What are the two types of dc armature windings? Simplex and lap; Duplex and wave; Lap and wave; Simplex and duplex; ... 3. If the armature consists of two separate windings insulated from each other and connected to alternate bars, this would be a ........ simplex double-reentrant lap. duplex single reentrant wave.

Types of armature windings ... Two types of windings mostly employed for drum-type armatures are known as Lap Winding and Wave Winding. The difference between the two is merely due to the different arrangement of the end connections at the front or commutator end of armature.

26.23) and is placed in the armature slot. It may be noted that .since the beginning and the end of each coil must be connected to a commutator bar. there are as many commutator bars as coils for both the lap and wave windings The side of a coil (1 -turn or multiturn ) is called a winding element. ...

The armature and field in a DC motor can be wired three different ways to provide varying amounts of torque or different types of speed control. The armature and field windings are designed slightly differently for different types of DC motors.
