What is the difference between the DC motor and AC motor?
• Need a transformer to convert the 110 volt (or 220 volt) AC input power to the low-level 12 volt (or 24 volt) AC power. • Then the regulator and filter convert it to the stable 12 volt (or 24 volt) DC power. • To use the DC voltage, it has the benefit: • The voltage deviation of the local AC power line has no affection on the motor operation. Therefore, The voltage deviation of the local AC power line has no affection on every tension pull. The AC (alternating-current) motor does not required to have the transformer, regulator and filter: • The 110 volt AC input power directly energizes the AC motor. • The voltage deviation of the local AC power line affects the AC motor turns. Therefore, the AC voltage deviation affects every tension pull. • Does the Hawk electronic tension head need 5 minutes warm up time? No, the Hawk electronic tension head utilizes the DC (direct-current) motor. It does not need any warm up tume at all. You just need to turn on the power switch and start to pull
