Title:
MULTI-STAGE MOTOR
Document Type and Number:
WIPO Patent Application WO/2014/051288
Kind Code:
A1
Abstract:
The present invention is a motor mounted on a shaft (S) of a fuselage (1) for generating power. The motor comprises: a magnetic force unit (10) which has a stator coil (11) fixed in a housing (H) and on the interior of the fuselage (1), and has a rotor (13) having a magnet (12) and designed to be rotatable from the stator coil (11); a main driving unit (20) which is integrally coupled with the rotor (13) having the magnet (12) of the magnetic force unit (10), and which receives rotating force from the magnetic force unit (10) to rotate the shaft (S); multiple auxiliary driving units (30a, 30b, 30c) which are arranged behind the main driving unit (20) to accommodate the shaft (S), and which have a planetary gear assembly (35) inserted into the center of the rotor (13) of the magnetic force unit (10) to selectively increase rotating force on the shaft (S); and a control unit (40) which detects and carries out calculations on the rotation direction, rotation speed and magnetic pole position of the magnetic force unit (10), outputs values to the main driving unit (20) and the auxiliary driving units (30a, 30b, 30c), and applies current to the magnetic force unit (10). Thus, the motor of the present invention may increase or decrease low rotating speed, high rotating speed and rotating force to enable efficient use of current. Furthermore, the motor can be formed into a small, medium or large size by the number of auxiliary motors, and therefore can be applied not only to the field of motor vehicles but also to other industrial fields.
