Motors Spec Table
The motor specification table provides reference data and selection criteria for stepper motors, AC servo motors, and BLDC motors. Steppers are suited for low-speed, low-cost positioning; servo motors for high-speed, high-precision control; BLDC for high-efficiency, long-life applications. Always verify the torque-speed curve and permissible inertia ratio when selecting a motor.

Frequently Asked Questions
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.
