Guide to the Power Circuit and Control Circuit of the Wound Rotor AC Induction Motor

In certain exceedingly enormous type of industrial applications where a tremendous amount of power is required to drive a specific type of load too large for the ordinary type squirrel cage induction motors to carry, the most appropriately preferred type of motor for use with such extensively large demand of power application is another type of large capacity motor which has the capability to run with high starting torque immediately attainable all throughout starting from when the motor is just beginning to run from rest even while it is at loaded condition up to when the motor reaches its peak rated speed while also carrying the same amount of heavy load, which would also necessitate for this type of motor to possess the ability to run continuously at different variation of steps of speed levels while driving a very heavy load. This type of motor is known as the wound rotor induction motor.

12 Leads Terminal Wiring Guide for Dual Voltage Delta Connected AC Induction Motor

The previous article presented the terminal wiring connection for a 12 leads star (wye) configured induction motor. Another type of 12 leads wiring configuration which is a distinguished counterpart to the star (wye) motor connection is the delta configuration. Again this type of connection will also have 12 wiring terminals directly accessible from the motor's terminal box which serves for external wiring purpose.

12 Leads Terminal Wiring Guide for Dual Voltage Star (Wye) Connected AC Induction Motor

Another convention of wiring connection for the AC induction motor apart from the 9 leads and the widely known 6 leads terminal is the 12 leads motor wiring connection. This can be determined directly by counting the number of available terminal leads accessible from the induction motor's terminal box.
