摘要
Abstract
The basic control principle of the DC starting motor is introduced in this paper. The weakness of the control cir-cuit of the electromagnetic switch used on the available starting motor is pointed out. A new digitized control circuit is put for-ward. DSP and MOSFET are used in this design to separate the switch signal from high-current coil control section in the control circuit of the electromagnetic switch,which can not only settle the problem that the high current pass through the control switch,but also settle the electromagnetic switch control problem when the starting motor pattern is various. This new control cir-cuit has the characteristic of simple control and is easy to put into effect. The experimental results show that this design can satisfy the design requirements.关键词
