Ø40-20215-24 brushless DC motor product technical manual, introduces the motor's extreme working parameters, inherent inherent characteristics, load working characteristics, electrical connection instructions and Hall output waveform
This manual provides an overview of the Φ40-20215-24 brushless DC motor, describing its three‑phase, six‑step, full‑wave Y‑shaped winding, sintered NdFeB permanent‑magnet rotor, and optional Hall‑sensor or sensor‑less operation. It also lists the motor's inherent characteristics such as resistance, torque and speed constants, and magnetic pole count.
Detailed sections include the motor's limit working parameters, load performance curves, electrical connection diagrams with Hall‑sensor wiring, cooling requirements, and dimensional data. Safety notices warn that exceeding temperature limits can cause permanent damage and that proper cooling must be installed when surface temperature exceeds 85 °C. This manual is written in Chinese.
