为了改变带式输送机传统驱动系统效率低、启动不平稳、重载启动困难等缺点，达到高效、节能、启动平稳、恒转矩控制的目的，永磁直驱系统采用了无齿轮永磁同步变频直驱系统，即驱动系统由永磁同步电机与变频器相结合实现动力的传递。由于去掉了减速器、液力耦合器，因此整个驱动系统具有低噪声、免维护、输出转矩大、启动平稳、恒转矩控制等优点。
為瞭改變帶式輸送機傳統驅動繫統效率低、啟動不平穩、重載啟動睏難等缺點，達到高效、節能、啟動平穩、恆轉矩控製的目的，永磁直驅繫統採用瞭無齒輪永磁同步變頻直驅繫統，即驅動繫統由永磁同步電機與變頻器相結閤實現動力的傳遞。由于去掉瞭減速器、液力耦閤器，因此整箇驅動繫統具有低譟聲、免維護、輸齣轉矩大、啟動平穩、恆轉矩控製等優點。
