INGCO S-ID-R-ID6008 Rotor

The INGCO S-ID-R-ID6008 Rotor is a component used in rotary hammers. Let’s explore some details about it:

Specifications:

• Model: S-ID-R-ID6008
• Type: Rotary Hammer
• Power Source: Electric (Corded)

The S-ID-R-ID6008 Rotor belongs to a special category of induction motors known as wound rotor induction motors or slip ring induction motors. Let’s explore its features:

1. Rotor Design:
   • The rotor of the S-ID-R-ID6008 is wound with three-phase insulated windings.
   • These windings are connected to slip rings via brushes.
   • The slip rings allow current to flow to and from the rotor winding.
2. Starting Torque Enhancement:
   • The primary purpose of a wound rotor motor is to provide high starting torque.
   • This is achieved by connecting an external resistance (via the slip rings) to the rotor circuit during startup.
   • The additional resistance in the rotor circuit allows the motor to develop significant torque while keeping the starting current moderate.
3. Rotor Resistance Control:
   • The speed of the wound rotor motor can be controlled by varying the resistance in the rotor circuit.
   • By adjusting the resistance, the motor’s speed can be increased or decreased.
   • This method is applicable only to slip ring induction motors.
4. Asynchronous Operation:
   • Unlike synchronous motors, wound rotor induction motors operate asynchronously.
   • Their operating speed is not equal to the synchronous speed of the rotor.
5. Stator Similarity:
   • The stator of the wound rotor motor is similar to that of a squirrel cage induction motor.
   • Both have the same number of poles.
6. Gradual Resistance Reduction:
   • During startup, the controlling resistance (star-connected rheostat) is gradually cut out as the motor gains speed.
   • This process balances torque improvement and reduction in rotor current.
7. Practical Applications:
   • Wound rotor induction motors find use in scenarios where starting current is too high compared to the power system’s capacity.
   • For example, they are employed in coal handling power plants for unloading coal efficiently.

Remember, the S-ID-R-ID6008 Rotor’s unique design allows it to deliver robust starting performance, making it suitable for specific industrial applications.
