Part winding starting This starting method requires a motor wound specifically for this application. It is not a reduced voltage technique. These special nine lead motors use only a portion (1/2 to 2/3) of their windings during starting. Starting torque is extremely low and the motor is not expected to accelerate.

What Is Motor Winding? Types of Motor Winding
Motors designed for "part winding start" utilize only a portion of the winding at start-up. This means a portion of the windings are energized with full load voltage. Since the windings are divided into two parallel circuits, the motor will only be exposed to a portion of the current at start-up depending on the design.

A part-winding starter will reduce starting current draw to approximately 65% of normal locked rotor amps, and torque to 45% of normal motor torque. A part-winding starter uses two contactors and a timer. Solid state reduced voltage starters (Soft Starts) utilize solid state devices called Silicon Controlled Rectifiers (SCR's) to increase and.

Also, since some part-winding start motors are numbered incorrectly as 1 to 6, remember the starting method you're using. 9 Leads. If leads are numbered 1 to 9, the motor is typically rated for two voltages and could be designed with either a wye or delta connection. Using the machine on the higher rating, the external connection is the same.

Oct 20, 2008. #4. No, a Part Winding motor starter is specifically for a motor configured for Part Winding (PW) start. Literally, the winding is split in two, so to start it you are connecting only a portion of it, then to run you connect the rest by just adding it in; no transition. There are two contactors, one for each part, and a simple timer.
Partwinding connection Electric motors & generators engineering
Part winding start is possible with motors whose stator winding is divided by design into 2 halves with 3 windings each. Both winding partitions lie parallel in the stator slots. During start, they are switched on one after the other, with a time delay of e.g. 0.5 .. 1 s.

Double Delta. Double Delta. This method accomplishes the equivalent of reduced voltage starting by changing a delta connected winding from parallel groups to series groups during the start. It is frequently termed "double delta part winding" because it utilizes a standard part winding starter and has characteristics that are similar to the part.

If the leads are numbered 1-3 and 7-9, the winding is capable of part-winding start. When using a different starting method (e.g., soft start, variable-frequency drive, or across-the-line), always connect the machine for run. Some machines will have 1-1, 2-2, 3-3, which will be a delta-run motor (see Figure 2).

Part winding starters, ill. 1, are designed to be used with squirrel cage motors having two separate and parallel stator windings. In the part winding motor, these windings may be Y connected or delta connected, depending on the motor design. Part winding starters are not suitable for use with delta-wound, dual-voltage motors.
