8-bit microcontrollers equipped with an oscillator circuit that provides more than twice the accuracy compared with previous models has been developed by LAPIS Semiconductor Co., Ltd., a ROHM Group ...

Generally speaking, three-phase motors are less troublesome than single-phase motors, having no starting relays or capacitors to deal with. All three-phase units are high-starting-torque motors and ...

However, while three-phase brushless DC (BLDC) motors offer better durability, noise level and controllability, their prices are higher than those of AC motors. Next, single-phase brushless DC motors, ...
