Software: Electric Drive Train Simulator (EDTSim)

Just found this cool little utility…  the Electric Drive Train Simulator (EDTSim) from Enigma Industries.  Here’s what the main screen looks like:

VERY cool little tool, only $35, and read all about it via the manual, here.

Among other things, you got this:

  • Includes four wheel car type and cycle type drive trains that can be used in designing electric go-karts, electric scooters or electric motorcycles.
  • Simulates battery voltage, state of charge, and internal resistance, so you can see how your bots (bikes) performance changes as the batteries run down.
  • Motor simulation allows you to see how motors will run at higher or lower voltages than the motor’s designed voltage.
  • Motor manufacturers rate motors in different ways making it difficult to compare motors.  In EDTSim all motors are rated in the same way, using the motor constants, making it easy to compare motors.
  • Large database of motors includes size, weight, torque, rpm, manufacturer, approximate price and places to buy them.
  • Motor performance and drive train acceleration graphs.
  • Large battery database includes size, weight, voltage, internal resistance, Peukert value and capacity at different discharge rates.
  • EDTSim takes into account motor, batteries and the electrical resistance of the speed controller and wiring and tells you the power of all the components combined.
  • Includes motor and battery editor so you can use manufacturer specs or test data to add motors and batteries to the database.
  • Includes example drive trains ranging is size from 1 to 360 lb and can be used for any size drive train that uses permanent magnet DC (PMDC) electric motors.
  • Includes twelve drive train configurations, two, four and six wheel tank or wheelchair type differential steering (also known as skid steering) drive train types with two, four or six motors. Two and four wheel car type Ackerman steering with front, rear and four wheel drive configurations.
  • Here’s what I liked best- the acceleration graph:


    One response to “Software: Electric Drive Train Simulator (EDTSim)

    1. So; Can you work up RPM required for needed speed (highway in CA), and they work up the battery load and thus expected range? If so, I think this might be the coolest program you have found so far!
