Security certification is becoming an increasingly important requirement for motor products, in which motor controllers must obtain UL/IEC Class B 60730-1 security certification. Motor controllers require both hardware and software for their operation. The HT32F65xxx series of MCUs provides a UL/IEC 60730-1 Class B motor control software security certification library.

This library comprises a complete suite of MCU self-check programs which include motor over-speed protection, motor lock rotor protection and running temperature protection. The MCU self-check parameters and the motor operation protection parameters can be easily adjusted by only modifying the library parameter settings.

Motor control and running real-time monitoring mechanisms are compatible with the HT32F Series BLDC Motor Workshop and secondary development space is retained for users. Different peripheral settings and control can be added according to specific functional requirements. The additional UL/IEC 60730-1 Class B parameter display platform provides the production line with a means of quickly detecting the accuracy of the product parameters.

Holtek is willing to provide professional technical services to assist users to import the UL/IEC 60730-1 Class B motor control security certification.
