  • Understanding Permanent Magnet Motors
    A permanent magnet motor is an ac motor that uses magnets imbedded into or attached to the surface of the motor's rotor. This article provides understanding behind the terminology, concepts, theory, and physics of PM motors.
  • AC Motors: Principle of Operation
    of pairs of poles and is always a ratio of the line frequency. The stator is provided with two simple coils, which can be directly connected to the mains. The rotor consists of a cylindrical permanent two-pole magnet, which is diametrically magnetized. Basic principles of Synchronous Motors
  • Sensorless Control of Permanent Magnet Motors (.pdf)
    Precise speed control of AC motors is typically accomplished with a variable frequency drive (VFD) connected to a speed or position feedback sensor. In certain situations, however, it's possible to achieve a similar level of precision speed control without the need for a feedback sensor via
  • Difference Between DC and AC Motor
    and DC brushless motors according to the type of steering gear. Among them, the stator of the brushed DC motor is a permanent magnet, and the rotor is a winding metal armature, which is commutated by carbon brushes and a commutator. The stator of the brushless DC motor is a winding coil, and the rotor
  • Sinusoidal Control of PMSM Motors with dsPIC30F DSC
    This application note describes a method of driving a sensored Permanent Magnet Synchronous Motor (PMSM) with sinusoidal currents controlled by a dsPIC30F Digital Signal Controller (DSC). The motor control firmware uses the dsPIC30F peripherals while the mathematical computations are performed
  • Sensored BLDC Motor Control Using dsPIC30F2010
    on BLDC motor details. BLDC motors are basically inside-out DC motors. In a DC motor the stator is a permanent magnet. The rotor has the windings, which are excited with a current. The current in the rotor is reversed to create a rotating or moving electric field by means of a split commutator
  • Integrated Stepping Servo
    be carried out. The main body of the stepping servo is a stepping motor, which is much cheaper and simpler in structure than the permanent magnet synchronous AC motor.
