NOVELTY - The motor comprises a magnetic tent, a coil, and a steering controller. The magnetic tent is composed of two units of permanent magnets. An N level of permanent magnet is oriented in the magnetic tent. A S pole of permanent magnet is oriented towards the magnetic tent. A coreless coil is placed in the magnetic tent with radial magnetic field through a rotating shaft. The rotating shaft is located at interval of two portion of permanent magnet. Two permanent magnet is composed of graphene sheets plated with neodymium iron boron. The coil is formed by winding by a graphene lead. USE - Coreless motor. ADVANTAGE - The working efficiency is high. The technical requirement of motor industry in energy-conserving is achieved. The light weight, little volume, long service life, and low production cost of motor is achieved.
