Function:

The rotor, also known as the armature, is a critical rotating component within the motor of an angle grinder. It works in tandem with the stator (stationary component) to generate the power required for grinding, cutting, or polishing.

Components:

A typical grinder rotor consists of these key parts:

• Shaft: A central steel shaft that provides the core structure for the rotor and allows it to spin within the motor housing. The grinding wheel or attachment is typically attached to this shaft.
• Laminated Steel Core: Similar to the stator, the rotor core is made from laminated electrical steel to minimize eddy current losses and improve efficiency.
• Commutator: This ring-shaped component, made of copper segments with insulating gaps between them, is mounted on the end of the shaft. It acts as a bridge between the rotor windings and the brushes (explained later).
• Rotor Windings: Copper wires are wound around the core, creating electromagnets. These windings are connected to the commutator segments. When current flows through the windings, they generate magnetic poles (north and south).

Operation:

1. When you turn on the grinder, electricity flows through the brushes (carbon or graphite contacts) which make contact with the commutator.
2. The current then flows through the rotor windings, creating magnetic poles within the rotor.
3. The stator’s rotating magnetic field interacts with the magnetic field of the rotor, causing a repulsive or attractive force between them.
4. Due to the commutator’s design and the interaction with the brushes, the polarity of the rotor’s magnetic field constantly changes as it spins. This continuous change in polarity allows for a unidirectional rotation of the rotor shaft.
5. The rotation of the rotor shaft is then transmitted to the grinding wheel or attachment of the grinder.
