        Drive System

        Water Cooling Motor Controller

        KAM has rich experience of nearly 10 years on development and improvements of drive system for electric vehicles. So far, KAM has developed a complete new motor controller which can be used for controlling both permanent magnet synchronous motor and asynchronous motor, the maximum output power is up to 240kW. This motor controller is compatible for the vehicles vary from 10meter to 18meter buses including double-desk buses. This system has been in production with die-casting mold and already be the standard product,no need to make any changes except software upgrades. With highly integrated design and convenient and fast installation, which only one box with all above functions, ,it’s definitely a convenient product for after-sale service in future.
