摘要： A stator and armature assembly 12 is provided for a permanent magnet DC motor. The assembly includes an armature 13 having a lamination core 14 and windings 15, and a stator structure 16 associated with the armature. The armature is constructed and arranged to rotate with respect to the stator structure. The stator structure includes at least one permanent magnet 22 providing a certain flux, and at least one wound core structure 17 having a core 18 and a coil 19 wound about the core so as to define an alternate pole with respect to the permanent magnet. When current to the coil is controlled, flux of the stator structure 16 can be increased or decreased relative to the certain flux. In this way a motor can operate at different speeds.

摘要： A dual motor arrangement includes a first motor M1, a first MOSFET Q1 constructed and arranged to control operation of the first motor, a second motor M2, a second MOSFET Q2 constructed and arranged to control operation of the second motor, an RFI filter structure L1, C_RFI, a freewheeling circuit L2, C2, and a controller S. The controller is constructed and arranged to provide a first PWM signal to the first MOSFET and a second PWM signal to the second MOSFET. The second PWM signal is in staggered time relation with respect to the first PWM signal. When one motor is in a freewheeling mode of operation for at least a portion of a time that the MOSFET, associated with the other motor, is on, freewheeling of the one motor decreases an amount of current drawn by the other motor during turn on of the other motor. The inductors L1, L2 can be coupled to define a transformer.

摘要： A cooling system includes multiple cooling fans, each driven by a corresponding fan motor controller. Each fan motor controller includes electronic commutation circuitry that is responsive to a modulated signal to control the speed of the associated motor and fan. The controller for one motor includes a microcontroller that receives a single control signal from an external control unit and translates that control signal into the modulated signals provided to all of the other motor controllers. In one embodiment, the microcontroller can adjust the duty cycle of the modulated control signals, and can stagger the on-off times of the signals to minimize conducted RFI emissions.
