Three Phase Squirrel Cage Induction Motor With Dol Starter Training System Direct on line (dol) starting is a method of starting an induction motor by connecting it directly to the power supply. this method is typically used for small squirrel cage induction motors with a power rating of up to 5 kw. There are four methods to start a squirrel cage induction motor. these are direct on line (dol), stator resistance, auto transformer, and star delta starting, while for a slip ring induction motor, we prefer rotor resistance starting.
Squirrel Cage Induction Motor Circuit Diagram This is a primary resistance starting and has a well proven french technology for soft starting of all types of induction motors. the device works on the principle of a decrease in resistance of an electrolyte (chemical) having a negative temperature coefficient. Technical specifications: motor type: 5 hp, 3 phase, squirrel cage induction motor voltage: 415v, 50hz speed: 1440 rpm input terminals: 6 terminals cooling: air cooled continuous rating: yes st. Explore dol, star delta, autotransformer, and soft starting methods for squirrel cage induction motors. learn about reduced voltage starting techniques. In this method of starting of a 3 phase squirrel cage induction motor reduced voltage is obtained by means of resistors (or reactors) that are connected in series with each stator lead, as shown in fig. 1.68, during the starting period.

It is simple, inexpensive and easy to install and maintain. it consists of a set of ‘start’ and ‘stop’ push buttons, a contactor (an electromagnet) with its associated contacts and usually overload and under voltage protection devices. the start button is momentary contact that is held normally open by a spring. Such a starting method, called the rotor resistance starter, cannot be employed in case of squirrel cage induction motors because external resistance cannot be introduced in squirrel cage motor. With direct starting, the poles of contactor and motor protective device are connected to the pole conductors (figure 1) and the operating current of the motor flows through them. the motor protective device must therefore be adjusted to the rated operational current of the motor.
