FAQ
What is integer slot winding and fractional slot winding?
Integer slot winding means that the number of slots per pole per phase g is an integer, and fractional slot winding means that the number of slots per phase per pole g is a fraction. Small and medium-sized motors are mostly integer slot windings (generally g=2～7). Only in certain circumstances, such as 6-pole and 8-pole motors using the same common iron core, the 8-pole motor needs to use fractional slot windings.
What is centralized winding and distributed winding?
When each pole and each phase winding only occupies one slot, that is, when g=1, it is called a concentrated winding; while each pole and each phase winding occupies more than one slot, and when g>1, it is called a distributed winding.
What is head and tail (polarity) of coil and winding lead wire?
The two lead wires of a coil, each of which can be called the head or tail, is non-polar. When the coil is embedded in the core slot and connected with other coils, it has a head and a tail. Generally, the lead section on the left-hａnd side of each coil in the iron core is set as the head, and the other lead is the tail. The polarity of the head and tail should be the same, otherwise the coil reverse connection fault will occur. The winding is made up of multiple coils in series in the forward direction, and the head and tail of the lead wire must be assumed to be consistent with the coil.
For the continuous winding (ie coil group), when embedding the first coil, the tie of the next coil should be loosened, and one turn of the wire should be pulled out for embedding. Therefore, when winding the windings, the first coil should be tied with full turns, and the remaining continuous coils should be wound by one more turn as a lead wire, and one less turn should be tied when binding. When embedding the wire, the first wire end of the first coil must be the head end.
