BLDC Motors and Hall Effect ICs

A BLDC motor represents a later technical development of the brushed DC motor where the brushes have been removed and has greater efficiency, longer life and greater torque. They are widely used in household appliances, industrial equipment and automotive devices, mainly because of their low-noise characteristics to prevent noise pollution and power-saving features thanks to high efficiency. Hall sensors such as Hall effect ICs or Hall elements are used for rotation control in BLDC motors. In BLDC motors, which are often called Hall motors, Hall effect ICs are used to detect rotor position to enable skillful control of when current is to be passed to the stator coils.

BLDC Motors and ZCL Hall Effect ICs

A wide variety of rotor design methods have been proposed for BLDC motors to reduce torque fluctuations and to lower the amount of rare metals required. However, the placement of magnets inside the rotor has made it difficult for Hall effect ICs to directly detect the magnetic flux of the rotor, or made it necessary to install them at an angle. ABLIC’s ZCL Hall effect ICs provide a solution to such problems in developing BLDC motors. ZCL (= Zero Crossing Latch) Hall effect ICs are Hall effect latch ICs that employ a world first detection method for changing the output signal at the point (= zero crossing point) where polarity changes. This Hall effect IC is specially designed for control of BLDC motors and provides stable detection not thrown off by changes in magnetic flux density.

Automotive,
high-efficiency, high-speed motors
S-57TZ S Series
A series of AEC-Q100 grade 0 qualified automotive ZCL Hall effect latch ICs.
These ICs change the output signal at the point where polarity changes (the zero-crossing point) and can therefore provide stable detection unaffected by magnetic flux changes. With a chopping frequency of 500kHz, these ICs are offered in two different lineups, either housed in a TSOT-23-3S or an HSNT-6 (2025) package. These ICs are designed to create automotive motors with ever greater efficiency
