SAKOR Applied sciences just lately supplied Nexteer Automotive with a dynamometer check system designed to check high-speed motors and inverters in hybrid and electrical automobile designs. Nexteer, a multibillion-dollar international steering and driveline enterprise, will use the dynamometer system to check its new line of full electrical automobile propulsion techniques.
The system will function a 164 kW AccuDyne 4 quadrant AC dynamometer to offer the required torque and most pace of 12,000 revolutions per minute (rpm). The check system additionally features a 175 kW, ±500 Vdc, 500 amp battery simulator.
The system will be simply upgraded at a later date to help greater speeds and higher energy densities if future designs require it.
The dynamometer and different subsystems are configured for electrical automobile motor testing and all the system might be automated by SAKOR’s DynoLAB check automation controller, a robust system that permits check engineers and/or technicians to design and implement advanced check procedures with out the necessity to study a programming language. Operators can shortly configure and run assessments utilizing the menu-driven interface.
The dynamometer is able to full bi-directional braking or driving of the gadget beneath check. It might additionally present full rated torque at stall (zero pace). The dynamometer options regenerative, non-resistive, energy absorption, with 360 N·m fixed torque from stall to 4,356 rpm. It presents a continuing energy of 164 kW from 4,356 to 12,000 rpm (steady obligation).
This new system might be extraordinarily helpful for performing design validation, in addition to figuring out efficiency, and sturdiness traits of assorted motor and inverter designs. It is going to contribute to understanding of learn how to design hybrid and electrical automobile drive trains that maximize effectivity and energy density whereas making the most effective use of restricted bodily area.
