product details:

Function:

The rotor resides within the motor housing and spins freely on a shaft. As electricity flows through the coils wrapped around the rotor’s core, a rotating magnetic field is generated within the motor. This rotating magnetic field interacts with magnets fixed on the stator (stationary component), causing the rotor to spin. This rotation is then transferred to the drill chuck via a gear reduction system, allowing you to drill holes at various speeds.

Design and Materials:

• Shaft: The rotor features a central steel shaft that allows it to spin freely within the motor housing. The shaft connects to the gear reduction system, ultimately driving the drill chuck.
• Laminated Steel Core: The core of the rotor is typically made from thin layers of steel, often with a silicon content. This design offers several advantages:
  • Strength: Steel provides a robust structure to withstand the centrifugal forces generated during rotation.
  • Reduced Eddy Currents: The lamination minimizes energy losses within the core due to eddy currents (electrical currents induced within the metal by the changing magnetic field).
• Commutator: A cylindrical component attached to the shaft and made from multiple copper segments. The commutator functions like a rotating electrical switch, reversing the current direction in the coils as the rotor spins. This current reversal is crucial for maintaining the rotation of the magnetic field and, consequently, the rotor’s continuous spinning motion.
• Coils: Copper wires wrapped around the laminated steel core form electromagnets when energized with electricity. The number of coils, thickness of the wire, and winding configuration significantly impact the motor’s characteristics like power output, speed, and starting torque.
