Electric Dynamometer: "Physical Examination Instrument" for Power Equipment
Just like using a treadmill to test a person's physical fitness, an electric dynamometer is a tool for "physical examination" of engines, motors and other equipment. It can simulate the load of the equipment when it is actually working, and measure various performance data at the same time.
The Core Components are Like the Human Body Systems
Motor (heart)
It is like a "two-way power bank" that can both generate electricity and use it:
When driven by the test equipment, it becomes a generator (mechanical energy → electrical energy)
When reverse testing is required, it becomes a motor (electrical energy → mechanical energy)
Loading device (dumbbell)
It is like weight equipment used in fitness, which uses electromagnets or resistors to generate adjustable "resistance" to simulate the various intensities of the equipment in actual work.
Control system (brain)
The built-in intelligent chip can adjust the load size thousands of times per second to ensure a stable and safe test process, and will immediately alarm when an abnormality occurs.
Measurement system (physical examination report)
The sensor displays data such as speed and power in real time, and automatically generates a test report with a curve graph, just like a smart bracelet records sports data.
Working principle
As the equipment is running, the dynamometer applies a controlled "burden" to it while recording:
How fast it rotates (rpm)
How much force was used (torque)?
Automatic calculation: Power = Speed × Torque ÷ 9550
Where is it used?
✔️ Car factory tests engine power
✔️ Drone manufacturers check motor efficiency
✔️ Quality control of power generation equipment before leaving the factory
It's like giving power equipment a "graduation exam" to ensure they are capable of doing the actual work.
