A diaphragm which has superior strength and rigidity is used suitably as the plane diaphragm 2, but the weight of the diaphragm is incremented by the weight of the permanent magnet to not always limit diaphragm with lightweight structure. The permanent magnet 1 is formed in a disk shape, magnetized from the center of the outer circumferences, and attached at the position corresponding to the oscillation knod of the plane diaphragm 2. The oscillation knod is the knod of split oscillation depending upon the shape, size, and rigidity of the diaphragm. The voice coil 3 is formed by winding a bobbin 6 with an insulating wire having thickness several times as thick as that used for a conventional movable coil type speaker.

IPC: H02P1/30
Filed: 1993-06-30
Abstract: PURPOSE:To obtain a motor controller which can suppress power consumption by performing rotary control according to starting pattern data selected according to the load of a motor from the activation start of the motor to normal operation. CONSTITUTION:When operation control is performed by the remote controller of an air conditioner, the data of indoor temperature and set temperature according to a remote controller are transmitted to a control part 10 of an outdoor machine following an operation command. Then, the control part 10 calculates the temperature difference between the indoor temperature and set temperature in cooling operation and then judges whether the difference is equal to or less than a specific value, reads the activation pattern data of a ROM part 9 based on the judgment result, and then determines the rotational acceleration pattern when starting a compressor motor 3. Then, when the difference between the indoor temperature and set temperature is extremely large, the rotational acceleration of the compressor motor 3 is rapidly increased after a specific time passes and rotational acceleration is increased somewhat gradually when the difference is small, thus suppressing power consumption on activation and at the same time improving the efficiency of the motor.
