Dynamometers Testing solution is a device used to measure 토크, 힘, 그리고 rotational speed of an engine, 모터, or other rotating machinery. Dynamometers are critical tools used in various industries, 자동차를 포함한, 항공우주, and industrial sectors, to test the performance, 능률, and reliability of engines, 모터, and drivetrains under different load conditions. Whether for R&디, production line testing, or regulatory compliance, a dynamometer provides accurate data that helps manufacturers optimize products for maximum efficiency and safety.
Principles of Dynamometers:
A dynamometers is a device used to apply a load or braking force on the test object， (such as motors, 엔진, mechanical systems, 등.) to measure its power and performance. The operating principle of a dynamometer usually relies on several methods:
Dynamometers typically classify into the following types:
Eddy-Current Dynamometer
자기 분말 동력계
Powder Brake Dynamometer
Hydraulic Dynamometer
Pneumatic Dynamometer
Factors to Consider When Selecting a Dynamometer
Dynamometers cover a wide range of Torque, 속도 및 기계적 동력 등급. selecting the appropriate size Dynamometer for your motor testing needs, you will need to determine the Maximum Torque, 속도 그리고 힘 applied to the Dynamometer:
It is important to consider all torque points that are to be tested, not only rated torque, but also Lock Rotor and Breakdown Torque. Dynamometer selection should initially base on the maximum torque requirement, subject to determining the maximum power requirements.
This rating is to be considered independent of 토크 and power requirements, and is the maximum speed at which the Dynamometer can be safely run under free run or lightly loaded conditions. It is not to be considered as the maximum speed at which full braking torque can appliy.
These ratings represent the maximum capability of the Dynamometer，Braking System to absorb and dissipate heat generated when applying a braking load to the motor under test. The power absorbed and the heat generated by the Dynamometer is a function of the Torque (T) applied to the motor under test, and the resulting speed (n) of the motor.

EconoTest manufactures four dynamometer families: 히스테리시스 동력계 (EC/ECO 시리즈) for precision low-torque testing, 와전류 동력계 (ECW 시리즈) for high-speed testing, 자기 분말 동력계 (ECF 시리즈) for high-torque low-speed and production line testing, and four-quadrant AC dynamometers (EC5A~EC2000A) for motoring and loading applications. All parameters are customizable upon customer requirements.
Hysteresis dynamometers cover 0.1–30 Nm; eddy current dynamometers cover 0.5–300 Nm; magnetic powder dynamometers cover 2–2,000 Nm; AC dynamometers cover 5–2,000 Nm. Together the range spans from 0.1 Nm micro-motor testing to 2,000 Nm heavy industrial applications.
Hysteresis and magnetic powder dynamometers both deliver full rated braking torque at zero RPM, making them suitable for starting torque, 코깅 토크, and locked rotor testing. Eddy current dynamometers cannot generate torque at zero speed because braking force depends on rotor motion. AC dynamometers can apply torque at zero speed in motoring mode.
Eddy current dynamometers reach the highest speeds — up to 50,000 RPM (ECW05KB). Hysteresis dynamometers reach 30,000 RPM (KB 시리즈) 또는 25,000 RPM (HB 시리즈). AC dynamometers cover 8,000–18,000 RPM. Magnetic powder dynamometers are limited to 2,000–5,000 RPM and are best for low-to-medium speed applications.
히스테리시스: ±0.5% 풀 스케일 (KB 시리즈) or ±0.2% (HB high-precision series). 와전류: ±0.2% to ±0.5% full scale. 자성 분말: ±0.2% to ±0.5% full scale. AC 동력계: ±0.20% full scale for both torque and speed.
Eddy current dynamometers are all water-cooled. 아래의 자성 분말 모델 20 Nm은 공냉식입니다., 20 Nm and above are water-cooled. Hysteresis cooling varies by model: 공기, 공기+물, water+blower or air+blower. Cooling requirements are specified per model in the technical documentation.
Absorption dynamometers (히스테리시스, 와전류, 자성 분말) can only apply braking load — they absorb energy from the unit under test and dissipate it as heat. A four-quadrant AC dynamometer can both load and drive the test article in both rotation directions, and recovers braking energy back to the grid, enabling efficiency mapping and hybrid powertrain simulation.
