<p>#CMT# #/CMT# The machine has a rotor (4), stator (5), and iron free magnetic coils connected with a control unit (6), where the electrical machine is made of two similar sub-machines. Field windings (5w) of two sub machines are arranged on a stator board (5p) facing each other. Permanent magnet rings (41, 42) are provided with a circular air gap. A part of the control unit is directly arranged at the magnet coils. Hall sensors are provided for rotational position determination of the rotor. #CMT#USE : #/CMT# Electrical machine e.g. hub motor, direct current motor and direct current generators, for driving a vehicle e.g. automobile, passenger car or a hybrid vehicle. #CMT#ADVANTAGE : #/CMT# The electrical machine has a simple structure and can be mounted in a simple manner. The electrical machine is made of two similar sub-machines, thus the electrical power transferred per field windings are halved, and hence reducing the thermal load of the magnetic coils, and improving the discharge of the loss heat by enlarging a radiation surface. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional representation of an electrical machine. 4 : Rotor 5 : Stator 5p : Stator board 5w : Field windings 6 : Control unit 41, 42 : Permanent magnet rings.</p> |
