Locked-rotor Protection
|
Over-current limiting circuit protects motor from damage at least for 72 hours of locked rotor condition at rated voltage.
|
under Locked Rotor |
A, Typical inrush current when the motor is trying to re-start under locked rotor conditions is 2~4 times the normal running
current reoccurring and for 16~20% of restarting cycle period. B, If he CL function is used this restarting inrush current is about the same as the normal running current. |
Reverse Polarity Protection
|
No damage if the positive and negative leads are reversed under maximum operation voltage conditions.
|
Over Voltage Protection
|
The circuit will be shut down automaticlly when input voltage over threshold. And re-started when Voltage down to threshold below.
|
Soft Start
|
In 5 seconds after power on and speed control voltage gets to 1.5V or PWM duty cycle at 10% above.

Q: What are electronically commutated motors?
Electronically Commutated motors are brushless DC motors where the direction of the electric current is switched using electronic controllers. As the switching of the current is technically known as 'commutating', brushless motors are also called 'electronically commutated' motors. EC motors provide the advantages of brushed DC motors in terms of the ability to have variable speed control, but without the drawbacks of brushes.
