EV Motors and Generators Panel Trainer by LJ Create
The electric motor and its associated power electronics are the heart of every battery electric and hybrid vehicle drivetrain. Understanding how motor speed is controlled, how position and speed sensors feed back to the drive system, how the inverter converts DC battery power to the 3-phase AC power the motor uses, and how the system behaves differently under throttle, braking, and drive select conditions is foundational knowledge for anyone working on EV drivetrains. And unlike conventional engine diagnosis, where years of familiarity with combustion engines gives technicians a solid intuitive foundation, EV motor and drive diagnosis requires deliberately building new mental models that most technicians do not yet have.
The LJ Create EV Motors and Generators Panel Trainer provides the hands-on investigation platform for building those mental models. It focuses specifically on motor speed control and uses a variety of sensors to feed back motor position and speed, illustrating electrical circuit operation under different operating conditions and providing test points for signal monitoring and fault-finding across the complete motor and drive system.
Klein Educational supplies LJ Create automotive training systems to automotive technology programs, community colleges, CTE programs, and workforce development centers across California, Oregon, Washington, Arizona, Nevada, Hawaii, and Alaska.
What is the EV Motors and Generators Panel Trainer?
The EV Motors and Generators Panel Trainer is a panel trainer focused on motor speed control and the sensor feedback systems that enable it. The trainer includes a variety of sensors for motor position and speed feedback, illustrates the electrical circuit operation of the motor and drive system under throttle, brake, and drive select conditions, and includes an inverter rectifier circuit for safe measurement of motor inputs at reduced voltages.
The trainer features encoder, resolver, and hall effect position and speed feedback devices, giving students hands-on experience with the three primary sensing technologies used across different EV motor designs. Understanding the differences between these sensor types, how they produce their signals, and how those signals are used by the motor controller is knowledge that directly supports diagnostic competency across the range of EV drivetrains students will encounter in their careers.
A simulated drivetrain shows motor speed control and the effects of regenerative braking in real time, and the trainer includes a schematic of EV circuits with test points throughout for signal monitoring and fault-finding. Students can test each phase of the 3-phase motor using the trainer's test point access, building the measurement skills needed to diagnose motor and inverter faults on real vehicles.
What students learn
The trainer supports instruction in EV motor operating principles and construction, inverter operation and DC to 3-phase AC conversion, encoder, resolver, and hall effect position and speed sensing, motor speed control under throttle, brake, and drive select conditions, 3-phase motor signal measurement and phase testing, regenerative braking system operation and generator mode, motor and drive circuit fault-finding using test points and appropriate equipment, and EV drivetrain diagnostic procedures.
