Symbol Name Description Open Switch An open circuit and shows no current is flowing. Closed Switch This means the circuit is complete, and the current is flowing. Telegraph Key Special electrical switch to send messages in morse code. Thermal Magnetic Switch During high current spikes...
A bulb as an electric symbol looks like a circle that has a cross in the middle, and it gives an output by getting light up when a current passes through it. Transformer Transformers are present in an AC circuit after being coupled by a magnetic flux. They reduce the tension in a ...

步进电机分三种:永磁式(PM)、反应式(VR)和混合式(HB)。 永磁式步进一般为两相,转矩和体积较小,步距角一般为7.5度或15度。 反应式步进一般为三相,可实现大转矩输出,步距角一般为1.5度,但噪声和振动都很大,在欧美等发达国家80年代已被淘汰。 混合式步进是指混合了永磁式和反应式的优点,它又分为两相和五相:...
