    The Permanent Magnet DC motor generally operates on 6 V 12 V or 24 Volts DC supply obtained from the batteries or rectifiers. The interaction between the axial current carrying rotor conductors and the magnetic flux produced by the permanent magnet results in the generation of the torque. The circuit diagram of the PMDC is shown below.

  • What is a permanent magnet What types are there

    A permanent magnet is a material that can provide magnetic flux when magnetized with an applied magnetic field and its magnetism capability is characterized by two key parameters remanence and coercitivity. In general the intrinsic coercitivity of a permanent magnet (Hcj ) is greater than 300kOe (in the CGS unit) or 24kA / m (in the SI unit).
