💡 What are the practical implications of the 70 kg.cm rated torque for a 1 cm lever arm in a DIY door lock or curtain automation project, and how does the self-locking worm gear respond when power is removed or when the load shifts?

Short answer: It provides solid holding power and controlled actuation within its rated torque, with the self-locking feature preventing drift when unpowered. Expect speed to slow as load approaches the limit, and consider heat and duty cycle when operating near stall.

• Under loads near the rated torque, speed will decrease as load increases; exceeding the rated torque can stall the motor or cause damage.
• Self-locking means the output shaft remains fixed with no electrical power, which is handy for locks and curtains that need to stay in place.
• Rotation direction can be altered by wiring configuration, simplifying installation in tight spaces.
• For longevity, avoid continuous near-stall operation; provide adequate cooling or use intermittent duty to prevent overheating.
