电机 规格表
3种规格数据
电机规格表整理了步进电机、AC伺服电机和BLDC电机的基本规格和选型标准。步进电机适用于低速低成本定位；伺服电机适用于高速高精度控制；BLDC适用于高效率长寿命应用。选型时必须确认扭矩-转速曲线和允许惯量比。
常见问题 (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.
