Endurance test stand for electric window lifters
Service life testing under realistic conditions: automated and accurate
- Type: endurance test stand, HiL test stand
- Device under test: DC motor for electric window lifters
- Test task: service life simulation in a climate chamber
Electric window lifters have to work reliably in all conditions, from freezing winters to hot summers in a closed car.
Manufacturers and suppliers therefore run service life tests to make sure the drives work without faults for years.
Typical test scenarios:
✔ Endurance runs with several thousand operations
✔ Loads at different temperatures and humidity levels
✔ Simulation of real operating conditions with variable load profiles
These tests are key for quality assurance, meeting OEM specifications and the release of new components.

The TMX endurance test stand in detail
The TMX endurance test stand for electric window lifters tests up to six motors in parallel under realistic loads. A climate chamber simulates temperatures from -40 °C to 100 °C, while a controllable brake and precise torque control reproduce real-world stress.
Test stand hardware
The test stand combines a two-stage climate chamber (-40 °C to +100 °C) with a modular test setup for up to six devices under test in parallel.
- Mechanical setup for realistic motion simulation
- Controllable brake to simulate variable load profiles
- Precise torque control
- Residual bus simulation via CAN/LIN
Automation and control
An industrial PLC with distributed measurement technology controls the test stand and captures high-accuracy sensor values.
- Open- and closed-loop control of motors, brakes and spindle drives
- Real-time measurement of torque, speed, motor current and temperature
- Automatic adjustment of test conditions to the test plan
Operating software
The intuitive test software makes tests easy to configure and documents them completely.
- Guided test sequences: simple setup and fast configuration
- Live data display: real-time monitoring of all measured values
- Automatic reports: professional test reports
Summary
The TMX endurance test stand for electric window lifters is a fully automated solution for service life testing. Modern measurement technology, flexible control and intuitive software make testing efficient, repeatable and realistic.
