From an idea to a fully functional prototype
What is the electric motor drive bundle?
The Electric Motor Drive Bundle is a ready-to-use reduced-scale prototype for control engineers. It features a fully programmable drive combined with a dual-motor test bench. The complete system easily fits in a laboratory and does not require any cumbersome infrastructure to operate. Plug the motor drive into a three-phase power outlet and start experimenting!
A motor drive system at the scale of your laboratory
Building a real-scale prototype of an electric motor drive system is time-consuming and expensive. It is especially true for large systems such as the electric propulsion of a car or a wind turbine generator.
A common trick to accelerate the development process is to validate the design on a functional prototype first.
Key technical specifications
- 4 kW electric machines
- 1800 rpm nominal speed
- Up to 800VDC operation
- 23.8 Nm maximum torque
The Electric Motor Drive Bundle is a ready-to-use solution for motor control prototyping. It includes an electric motor drive, a pre-built motor test bench, and turnkey code examples.
The digital controller allows the implementation of the most advanced control techniques on both the DSP and FPGA. Programming is possible using Simulink, PLECS, or C/C++ code.
The built-in hardware protections are user-programmable and instantaneously switch off the power stage to prevent inappropriate operation. A brake is also available for emergency braking.
Test your electric motor drive on actual machines
Spin real motors in your lab
While simulation provides meaningful insights into the operation of a system, experimental results are still the only way to validate a control algorithm. Unfortunately, building a motor prototyping setup requires significant work for the mechanical design.
Imperix offers a turnkey solution to bypass this inconvenience and start spinning real motors in no time. The Motor Testbench is a pre-built system featuring two industrial-grade machines. Forget about mechanics and jump straight into control algorithm design.
- 4 kW squirrel cage induction machine
- 4 kW permanent magnet synchronous machine
- Bidirectional torque sensor
- 2x PT1000 temperature sensors
- Resolver (position sensor)
- Built-in brake
Some motor drive systems make use of a mechanical brake for safety purposes. Typical use cases include locking an elevator in place in case of a power failure or performing an emergency braking with an electric vehicle. Thus, the Motor Testbench features a built-in brake to perform these functions if needed.
The machines are mounted on a robust aluminum frame to absorb vibrations and abrupt torque variations. Additionally, transparent protective plates enclose the shaft to prevent accidental access to spinning parts during operation. Finally, each motor has a built-in temperature sensor to monitor the temperature of the windings.
