Speed Control System of DC Separately Excited/Series Excited Motor for Electric Vehicle Introduction Jinan Keya Company specializes in producing speed controller and its auxiliary products for electric vehicle. With self-developed patent, the Company can make varieties of speed controller for purpose of electric vehicle, which mainly include series excited permanent magnet motor controller and separately excited motor controller applied to the motion and regulation of electric tricycle, industrial or mining trailer, porter, golf car, electric shovel loader, dune buggy, electric field service vehicle and electric forklift. Technical Parameter: Applicable Voltage Range: ±*0% of operating voltage Output voltage: zero to set value Ambient temperature: **0~**5℃ Maximum allowable temperature: *5℃ Speed regulation signal type: **1 is potentiometer *0K /2W, **3 is Hall handle, **4 is pedal accelerator, **2 is signal isolator（0~5V、0~*0V、4~*0mA） Speed regulation ratio: 1:*0 Ambient humidity: non-condensing Ⅰ.Summary The circuit is designed for battery-powered low-voltage high-power direct current motors, use of micro-processing chips and PWM impulse width special chip integration, signal processing, sampling to protect and promote the circuit more complete and reliable, while improving energy efficiency Conversion ratio. Ⅱ. Application Cope Can be used in mining trailers, cars, golf carts, electric forklifts, beach vehicles, etc. and others. Ⅲ. Feature 1. Voltage monitoring functions: Detection of the RMS voltage battery, battery when stopped in the low voltage output, effective protection of a battery of losses, damage, improved battery life. 2. High ability effect conversion ratio Using a dedicated low-power circuits and high-power devices and greatly reduce the driver's own energy consumption, improve energy efficiency ratio. 3. Over-current function and over temperature function 4. Built-in-charge resistance, polarity protection dio
