Electric Motor Testing with a Dynamometer
A motor dynamometer, or dyno for short, is an electromechanical device that measures the overall performance characteristics of a motor. It simultaneously measures the rotational speed and torque. With the addition of other bench top equipment and electronics we can also measure power, current draw, and operating efficiency across the entire torque range. All of the data is then exported to our validation software where we can then extrapolate a detailed motor performance curve.
Our electric motor dynamometer testing allows us to evaluate dc gear motors & dc motors to ensure projected performance data is accurate. This can be useful for multiple situations like evaluating first article samples, comparing two different motors, diagnosing a field failure, or simulating a particular duty cycle.
When a motor is designed for the first time, a lot of the calculations are based on prior designs, experience and mathematical calculations. Brake dynamometers, like ours, are excellent electric motor testing devices that allow manufacturers to prove those theoretical calculations in a more realistic setting, proving the motor or gear motor is operating as it was intended.
Testing Capability Guidelines
We provide our testing services to customers for a wide range of brushed-dc motors and brushless dc motors along with gear motors. This service is great for customers that have a specific incumbent motor or gear motor that needs to be tested.
Our motor testing equipment is designed for our most prominent product offering, so we do have some testing limitations. Below you will find guidelines and parameters that encompasses our current testing capabilities:
- Peak Operating Voltage: < 48VDC
- Current Draw: < 30A
- Input Power: 900W (max)
- Torque: up to 120 kg.cm
- Speed: up to 10,000 rpm
- Physical Size: 10mm – 52mm diameter (inline types)
*NOTE: If your motor or gear motor requirements fall outside of these guidelines, please contact ISL Products . If we are unable to do a complete evaluation, partial testing may still be possible dependent upon your request. Our advanced motor testing tools and capabilities are constantly expanding so its always best
