AC induction motor controller of electrical vehicles

Product introduction

The Land Ranger series Electrical Vehicle controllers can be used for the driving of Induction Motor, PMSM and BLDC, which are widely used for Forklift truck, Golf vehicle, electric touring bus, electric sightseeing bus, electric patrol vehicle, etc. The controller has the following advantages in smart volume, high efficiency, high performance, high reliability, etc. The controllers enable the electrical vehicles operation at a fast acceleration, clamping, frequency action, four-quadrant operation, etc. The Land Ranger systems improve the efficiency of the actual motion at working condition, and the controller could output the motive power when the batteries energy are low.

The system provides short circuit protection, over current protection, locked-rotor protection, battery over/under voltage protection, over speed protection. Furthermore, the controller system offers self- diagnosis and error indicator (LEDs) for safety operation. The controller use AMP-35PIN interface, provide CAN communication, waterproof design and excellent EMC property.

The intelligent torque control. The torque control enable the customer demarcate the proper acceleration curve to meet the requirement of the application. The Land Ranger series controller can output smooth torque with a fast dynamic response whenever the acceleration pedal are trample slowly, trample suddenly, lift up slowly and lift up suddenly.Four-quadrant operation and battery energy charging can be achieved for all type of machines whenever the electric brake mode is selected.Creeping control. The Lang Ranger series controller offers the function of imitating the traditional vehicle creeping steer.Intelligent voltage control. The Lange Ranger series provide intelligent voltage control. The controllers can proper output at nominal condition unless the battery voltage drops 13% of the rated voltage. The battery protection is active and the controller will goes into the low voltage mode whenever the battery stays at a relative low voltage condition.
