What are the advantages of asynchronous motors over traditional permanent magnet motors? Dalan motor manufacturer to answer!
Permanent magnet motors are synchronous motors. The rotor uses permanent magnets, and the stator generates electromagnetic torque to push the magnetic field of the rotor to rotate around the axis, and the magnetic fields of the stator and the rotor are synchronized. The induction motor is an asynchronous motor, which is an AC motor in which the rotating magnetic field formed by the stator winding interacts with the magnetic field of the induced current in the rotor winding to generate electromagnetic torque to drive the rotor to rotate. So what are the advantages of asynchronous motors compared to them? Asynchronous motor advantage one: Can tolerate large operating temperature changes. Conversely, large temperature changes can damage permanent magnet motors. Asynchronous motor advantage two: The output torque of the asynchronous motor can be adjusted in a wide range, so there is no need to install a second or even a third set of transmission mechanisms. The output torque can be forced to increase when accelerating or climbing (although the time is very short), while the permanent magnet motor electric vehicle needs to output more torque through the gearbox to achieve speed increase. Asynchronous motor advantage three: Small size and light weight. On the one hand, due to the large temperature tolerance range, the electric motor does not need to install radiators, cooling fans, water pumps and related pipelines like other electric vehicles. On the other hand, there is no need to install redundant transmission mechanisms. Therefore, its motor volume and weight are greatly reduced. The asynchronous motor is similar in size to a watermelon and weighs only 52 kilograms. All in all, Dalan motor manufacturers have concluded that the motor power system of asynchronous motor has the advantages of reliable operation, light weight and low price, and has been widely used. ï¼ï¼ï¼ï¼ Responsible editor: Dalan Oil Pump Motor 02-Procurement Consultant Copyright http:/(Dalan Motor) Please indicate the source for reprinting The Schottky Diode is another type of semiconductor diode which can be used in a variety of wave shaping, switching and rectification applications the same as any other junction diode. The main adavantage is that the forward voltage drop of a Schottky Diode is substantially less than the 0.7 volts of the conventional silicon pn-junction diode.
Schottky diodes have many useful applications from rectification, signal conditioning and switching, through to TTL and CMOS logic gates due mainly to their low power and fast switching speeds.
the Schottky Diode also known as a Schottky Barrier Diode is a solid-state semiconductor diode in which a metal electrode and an n-type semiconductor form the diodes ms-junction giving it two major advantages over traditional pn-junction diodes, a faster switching speed, and a low forward bias voltage.

The metal–to-semiconductor or ms-junction provides a much lower knee voltage of typically 0.3 to 0.4 volts compared against a value of 0.6 to 0.9 volts seen in a standard silicon base pn-junction diode for the same value of forward current.
Variations in the metal and semiconductor materials used for their construction means that silicon carbide (SiC) Schottky diodes are able to turn [ON" with with a forward voltage drop as little as 0.2 volts with the Schottky diode replacing the less used germanium diode in many applications requiring a low knee voltage.
