A power transistor, commonly a MOSFET (or IGBT), serves as the switching component in BLDCs. It switches the driving current to generate and deplete electromagnetic fields in the stator coils, which are revolving around the rotor made of a permanent magnet.
A three-phase, one kW BLDC motor, The maximum current at 48 Vdc should be around 25 Amps, with a peak current of 50 Amps for brief periods. However, I discovered 24-device MOSFET controllers with four IRFB3607 MOSFETs each phase (4 x 6 = 24) while researching BLDC motor controllers.
A brushless DC motor, also referred to as a BLDC, is a permanent magnet synchronous electric motor that is powered by direct current (DC) electricity. Commutation, which is the process of producing rotational torque in the motor by changing phase currents through it at the proper times, is controlled electronically by the BLDC.
The Global BLDC motor MOSFET market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
A new 40V Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) has been made available by Magnachip to operate Brushless Direct Current (BLDC) motors for automotive applications.
To lower the conduction loss of automobile BLDC motors, Magnachip created a new 40V MOSFET with low RDS, and the business has started mass producing it. The new 40V MOSFET is fully AEC-Q101 certified because dependable automotive semiconductors are essential for vehicle safety.
The electric water pump of a brand-new EV vehicle from a major automaker is the initial use for this innovative device. Several BLDC applications, including electric oil pumps, engine cooling fans, electric power steering, and battery cooling fans, are also compatible with this MOSFET.
