  • Frameless or Framed Motors ..... Which is right for you?
    magnets are used for high speed motors to ensure magnet retention at any speed and environmental conditions. For AC motors, the rotors assemblies are manufactured with squirrel cage rotors utilizing either molten aluminum or copper alloy bars. ARC's rotors are skewed using highly designed stacking
  • What are Brushless DC Motors and how do they work?
    together.  Coils of insulated magnet wire are inserted inside the slots. The currents flowing in the stator establishes a rotating magnetic field in the air gap thereby inducing voltage into the rotor conductors. The induction motor rotor consists of either copper or aluminum bars connected
