A synchronous motor employing a direct current (DC) electric power source is referred to as a brushless DC electric motor (BLDC motor or BL motor), sometimes known as an electronically commutated motor (ECM or EC motor), or synchronous DC motor.
It uses an electronic controller to switch DC currents to the motor windings, creating magnetic fields that, when the permanent magnet rotor follows them, effectively rotate in space.
To regulate the motor’s speed and torque, the controller modifies the DC current pulses’ phase and amplitude. The mechanical commutator (brushes) found in many conventional electric motors can be replaced by this control system.
A brushless motor system is often built similarly to a permanent magnet synchronous motor (PMSM), although it can also be an induction motor or a switching reluctance motor.
Additionally, they could be axial (the rotor and stator are arranged in a straight line) or outrunners (the stator is ringed by the rotor), all of which make use of neodymium magnets.
The global construction equipment BLDC motor 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.
Volume shipments of the “TC78B011FTG” three-phase brushless DC motor control pre-driver IC from Toshiba Electronic Devices & Storage Corporation (“Toshiba”) began.
The item is for high-speed motors, such as the blowers and fans used in servers as well as the suction motors in cordless and robotic vacuum cleaners.
The sine-wave driving approach used by TC78B011FTG does not rely on Hall sensor control. This lessens noise and vibration.
Additionally, a built-in closed loop speed control function enables the programming of a thorough speed profile into the IC’s non-volatile memory (NVM), assuring suppression of rotation speed variations caused by variations in load or power supply voltage without the need for an external MCU.
Toshiba also makes the TC78B009FTG in large quantities, which uses a rectangular-wave driving technique that does
