起动方式的选择主要包括直接起动和间接起动两种。
即IC611。电动机允许在额定电压和额定频率下直接起动。
The motor is permitted to directly start in conditions of rated voltage and rated frequency.
可控制交流50Hz,380V,三相异步电动机的直接起动停止,并具有过载和断相及失压保护。
Able to directly control AC 50Hz, 380V asynchronous motor with the protection of overload, phase-failure and voltage-absent.
对电动机的直接起动、传统降压起动方式、起动方式进行对比,介绍了软起动器的起动模式、运行模式及适用场合。
Through comparison among direct starting, conventional reduced voltage starting and electronics starter, this thesis described starting mode, run mode and application location of soft starter.
据此仿真模型,进行了并励直流电动机的直接起动、降压起动、电枢回路串电阻起动的实例仿真实验,给出了有关仿真结果。
Then the model is applied to simulate the direct start-up process, the reduced voltage starting process and the starting process with series resistance in the armature circuit.
通过电动滚筒驱动的皮带机,如果直接起动,无法根据物料比重调节速度,无形中造成了电能的浪费,而且会缩短电动滚筒的使用寿命。
If we directly start the belt-driver which is driven by electric-roller, it can neither adjust speed according to the proportion of materials, nor prolong the life of electric-roller.
