  2. Permanent magnet motor - Wikipedia

    en.wikipedia.org/wiki/Permanent_magnet_motor

    A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology.

  3. Brushless DC electric motor - Wikipedia

    en.wikipedia.org/wiki/Brushless_DC_electric_motor

    The motor from a 3.5 in floppy disk drive. The coils, arranged radially, are made from copper wire coated with blue insulation. The rotor (upper right) has been removed and turned upside-down. The gray ring inside its cup is a permanent magnet. This particular motor is an outrunner, with the stator inside the rotor. DC brushless ducted fan. The ...

  4. Magnet motor - Wikipedia

    en.wikipedia.org/wiki/Magnet_motor

    A magnet motor or magnetic motor is a type of perpetual motion machine, which is intended to generate a rotation by means of permanent magnets in stator and rotor without external energy supply. Such a motor is theoretically as well as practically not realizable. [1] [2] The idea of functioning magnetic motors has been promoted by various ...

  5. Synchronous motor - Wikipedia

    en.wikipedia.org/wiki/Synchronous_motor

    A permanent magnet synchronous motor and reluctance motor requires a control system for operating (VFD or servo drive). There is a large number of control methods for synchronous machines, selected depending on the construction of the electric motor and the scope. Control methods can be divided into: [21] [22] Scalar control. V/f control ...

  6. High efficiency glandless circulating pump - Wikipedia

    en.wikipedia.org/wiki/High_efficiency_glandless...

    The primary design factors of a high efficiency glandless circulating pump include an electronically commutated synchronous motor, a permanent magnet rotor, and canned rotor technology. An electronically commutated synchronous motor is used to convert the energy current from a DC energy source into an AC current which is supplied to the drive ...

  7. MEMS magnetic actuator - Wikipedia

    en.wikipedia.org/wiki/MEMS_Magnetic_Actuator

    The applied force depends on both the field from the coils and the magnet. The remanence value of the magnet, [4] its volume and position from the coils all contribute to its effect on the applied Force. Whereas the number of turns of coil, its size (radius) and the amount of current passing through it determines its effect on the Applied Force.

  8. Surface-mount technology - Wikipedia

    en.wikipedia.org/wiki/Surface-mount_technology

    Surface-mount technology (SMT), originally called planar mounting, [1] is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). [2] An electrical component mounted in this manner is referred to as a surface-mount device ( SMD ).

  9. TEFC motor - Wikipedia

    en.wikipedia.org/wiki/TEFC_motor

    Oil Well Pump Motors – Severe Duty Motors – Pool Pump Motors – One of the quietest motor pump on the market, due to its permanent magnet motor and TEFC design; Compare to the ODP (Open Drip Proof) motor design, which has ventilation openings which are guarded to prevent falling water from entering the motor windings.
