電機 規格表
3種規格資料
電機規格表整理了步進電機、AC伺服電機和BLDC電機的基本規格和選型標準。選型時必須確認扭矩-轉速曲線和允許慣量比。
常見問題 (FAQ)
What is the difference between a stepper motor and a servo motor?
Stepper motors use open-loop control, ideal for low-speed precise positioning at low cost. Servo motors use encoder feedback for high-speed, high-torque, high-precision control — but at higher cost.
What are the advantages of BLDC motors?
No brushes means longer life and less electrical noise. High efficiency (90%+) with compact, lightweight design — widely used in robots, drones, power tools, and medical devices.
How do you calculate the required motor torque?
Required torque (N·m) = moment of inertia (kg·m²) × angular acceleration (rad/s²) + load torque. Apply a safety factor of 1.5–2×. With a reducer: output torque = motor torque × reduction ratio × efficiency.
