SS400/SS4/SS1 series switch Hall sensors from Honeywell can replace mechanical commutation in DC motors. They are low cost, have very low-gauss number of action and release points, and, when combined with low-power semiconductors, make brushless DC motors extremely price-competitive in the motor market.
The SS400/SS4/SS1 series are low‑cost bipolar Hall‑effect sensors designed to replace mechanical commutators in brushless DC motors. They provide precise rotor position data with very low Gauss actuation and release points, making them suitable for a wide range of motor applications.
The document covers the operating principle of brushless DC motors, typical three‑phase drive circuits, and detailed installation guidelines, including sensor spacing, mounting options, and temperature considerations. Technical specifications such as supply voltage, temperature range, and pin dimensions are also provided. This manual is written in Chinese.
