Electric motor

It is equipped with three smart IFXT half-bridges. Alternatively, it can be used to drive one or two bi-directional DC motors H-Bridge configuration, cascaded to support second motor or up to three uni-directional DC motors half-bridge configuration. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, and dead time generation. The three IFXT half-bridges are also fully protected against over-temperature, under-voltage, overcurrent and short circuit events. Watch how easy it is to connect the IFXT shield to an Arduino and to use it to make a delicious mango lassi with a 24V smoothie maker.

Matteo Notarnicola. Iustin Radu Bojoi. Politecnico di Torino, Corso di laurea magistrale in Ingegneria Elettrica, Brushless motors are a growing technology that is used to replace old, less performing DC motors. Their structure is based on a three-phase synchronous stator with a rotating magnetic field supplied by the stator windings and permanent magnets hooked to the rotor structure. However, the term Brushless refers to an electrical drive with position feedback, which includes power conversion stage, motor, load, sensor and all the accessories. The work brought on aimed to implement a sensorless control, independent from the use of position sensors on the motor and therefor flexible and versatile for a multiplicity of motors.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Electric motors can be powered by direct current DC sources, such as from batteries, or rectifiers , or by alternating current AC sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless , may be of various phase see single-phase , two-phase , or three-phase , and may be either air-cooled or liquid-cooled. General-purpose motors with standard dimensions and characteristics provide convenient mechanical power for industrial use.


In case of permanent magnet motors, usually speed control is achieved by using proportional-integral (PI) controller. Although conventional PI controllers are.

Woodbank does not monitor or record these emails. Brushless motors such as permanent magnet and switched reluctance motors depend on electronic drive systems which produce rotating magnetic fields to pull the rotors around. The advent of new magnetic materials such as alloys of Neodymium with high levels of magnetic saturation and high coercivity , able to set up and maintain high magnetic fields, have enabled a range of innovative brushless motor designs by eliminating one set of the traditional motor's windings, either the stator or the rotor. The implementation of many of these brushless designs however has only been made possible by the availability of inexpensive high power switching semiconductors which have enabled radical new solutions to the commutation problem and much simpler mechanical designs. By using permanent magnets, rotor windings and mechanical commutation can be eliminated simplifying manufacture, reducing costs and improving reliability.

Our team of engineers understands the demanding requirements for a wide range of industries and applications. Let us solve your application challenge. A manufacturer of CBD distillation equipment required a drive system to precisely control flow and speed of liquids.

Moreover, in many applications to reduce the cost and enhance the reliability of drive, sensorless control techniques are used. This paper proposes a novel sensorless control for a nonsinusoidal PMBL motor with minimum torque ripple. To develop smooth torque, the selected torque harmonic elimination strategy is employed.
