Over-current fault protection
Most motor controls require over-current fault protection. There are many reasons for overcurrent faults, such as motor winding short circuit, motor lead short circuit, mechanical drive and connection device failure, power device damage, wiring errors, etc. A serious overcurrent fault will cause damage to the electrical appliance. Therefore, when an overcurrent fault occurs, no matter what the cause is, the motor must be stopped immediately to prevent damage. Although the protection circuit must act quickly, it is better to turn off the output on a cycle-by-cycle basis to resume normal operation when the fault condition can no longer be detected, rather than shutting down the entire system completely in one fell swoop. If this method does not resolve the problem, then shut down the system.
This motor controller solution uses a sensing resistor to measure the motor current (picture) and transmit the signal to the on-chip integration. The overcurrent threshold can be set, and once the current reaches this threshold, the system will start an interrupt service routine, then terminate the trigger pulse sent to R, and finally shut down the system.
Zero-crossing point
To control the motor speed, the firing angle of R must be synchronized with the AC circuit voltage, therefore, the zero-crossing moment of this signal must be determined. The motor control solution uses an on-chip integrated analog comparator, eliminating the need for external components, thus helping to reduce cost and system complexity. The figure shows the different R firing angles used to achieve variable speed control. In the application shown in the figure, the firing angle of R is set to .
