This product manual provides detailed information about the characteristics, extreme working parameters, inherent characteristics, external dimensions, load working characteristics, electrical connections and other information of YS50-40258-220 DC brushless motor
The YS50-40258-220 is a three‑phase, six‑step, brushless DC motor with Y‑shaped winding, sintered ferrite‑boron permanent‑magnet rotor, and integrated Hall sensors. It is designed for very low cogging and can be customized for specific applications.
The manual provides the motor’s electrical connection diagram, Hall sensor wiring colors, performance curves (speed‑torque, current‑torque, efficiency), and safety warnings such as the need for additional cooling if the surface temperature exceeds 85 °C. Contact information for Beijing Yilitaida is included at the end. This manual is written in Chinese.

The motor’s peak current is 4.5 A.
The coil and rotor may operate from –20 °C to +130 °C, while the ambient temperature should stay between –20 °C and +85 °C.
The Hall sensor wires are color‑coded: A‑phase sensor (blue), B‑phase sensor (yellow), C‑phase sensor (green), power (red), ground (black), and must match the controller’s phase order.
At the rated 220 V, the motor can deliver up to 507 W of output power.
