Ac Wound Rotor Motor Wiring Diagram Free Picture

The resistance can be adjusted to control the speed torque characteristis of the motor.

Ac wound rotor motor wiring diagram free picture. The ac line is directly connected to the stator of a repulsion motor with the commutator shorted by the brushes. The wound rotor motors use resistor to connect the rotor windings. As the motor accelerates. Most wound rotor motors are used where high starting torque is required so an altivar 312 altivar 32 or altivar 71 drive would be most suitable for this application.

A wound rotor motor also known as slip ring rotor motor is a type of induction motor where the rotor windings are connected through slip rings to external resistance. Their sole purpose is to allow resistance to be placed in series with the rotor windings while starting figure below. For most shore facility applications this is the case. Long motor life is ensured with the use of external resistor banks or liquid rheostats that dissipate heat build up generated during motor start up.

These slip rings are attached to brushes and variable power resistor banks where operators can change the speed of the motor by varying the resistance through the rotor coils. 3ø wiring diagrams 1ø wiring diagrams diagram er9 m 3 1 5 9 3 7 11 low speed high speed u1 v1 w1 w2 u2 v2 tk tk thermal overloads two speed star delta motor switch m 3 0 10v 20v 415v ac 4 20ma outp uts diagram ic2 m 1 240v ac 0 10v outp ut diagram ic3 m 1 0 10v 4 20ma 240v ac outp uts these diagrams are current at the time of publication.

Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit. This is known as a universal motor. The stator is in the stationary electrical component. Retractable shorted brushes may start a wound rotor induction motor.

In wound rotor motors the rotor is wound with wire similar to the stator with their terminal ends connected to 3 slip rings on the output shaft. The basic diagram view a shows a circle with two leads labeled t1 and t2. This is known as a repulsion start induction motor. A wound rotor induction motor has a stator like a squirrel cage induction motor but a rotor with insulated windings brought out via slip rings and brushes.

Adjusting the resistance allows control of the speed torque characteristic of the motor. What makes the wound rotor motor a unique induction machine is its rotor. Wound rotor motors also can develop high starting torque at standstill while maintaining low inrush. A stator and a rotor as shown in figure 8.

An ac motor has two basic electrical parts. Just as in the three phase motor diagram the motor shows the power supply lines as being identified with the t. It consists of a group of individual electro magnets arranged in such a way that they form a hollow cylinder with one pole of each magnet facing toward the center of the group.

However no power is applied to the slip rings.
