ROTOR OF ELECTIRC MOTOR FOR SIMPLIFIED MANUFACTURING PROCESS AND ELECTRIC MOTOR HAVING THE SAME

摘要

A rotor and an electric motor having the same are provided to delete the existing sensor magnet by improving the structure to detect the location of the rotor from the magnet member which generates the rotating torque. A rotor of an electric motor includes a laminated core(141) and a pair of magnet members(144). The laminated core is laminated by a plurality of piece cores(142). The magnet members generate the rotating torque by the electro magnetic interaction with a stator. The pair of magnet members are formed on the laminated core to detect the magnetic flux by the magnetic sensor and has the opposite magnetic pole each other. One of the magnet members has a projected unit(144a) which is projected to the magnetic sensor from the laminated core.
