CAMA the only one eddy current dynamoameter manufacturer in the world that can compare with and same to that of AVL, because two companies' eddy current dynamometer technology were same introduced from Germany Zollner.
CAMA (Luoyang) Electromechanic Co., Ltd (Original named Nanfeng), affiliated with China Airborne Missile Academy, is the biggest and leading engine test bench manufacturer in China.
CAMA exclusively introduced eddy current dynamometer technology from Germany ZOLLNER GMBH in 1988. With military manufacturing history of fifty-year, advantage of quality control system in airborne enterprise, CAMA successfully sold about 5000 engine test benches to more than 800 customers all over the world.
Series CW eddy current dynamometers, which produced by our company and manufactured according to the proprietary techniques of ZOLLNER GMBH in Germany, have advantages of low inertia, high accuracy and stability, simple structure, convenient maintenance, complete series, wide use, automation in operation and control etc.
The dynamometers are not only used for testing and performance test of engine but also in the fields of performance test, survivability test, model test of other prime mover, dynamo, rotational system and some components and parts like oil pump, oil nozzle, speed governor and so on. They are widely used in production, scientific research, education, maintenance and other fields.
CAMA develops constantly, not only serializes of types, but also designs, produces and installs complete test-bed of dynamometer for customers. With high technology, integrated engineering strength and rich experience, NF company can produce high-level testing equipments to serve customers sincerely.
Nowadays CAMA eddy current dynamometers hold over 85% market share in China, products are exported to America, Australia, Russia, Turkey, Malaysia, Vietnam, Laos, etc. About 5, 000 sets of CAMA eddy current dynos are running in CAMA's more than 800 customers' company.
Key technical indexes of the eddy current dynamometer:
Measurement accuracy of the torque of the system is better than ± 0.2%FSR
Measurement Sensitivity of the torque is better than ± 0.1%FSR
Measurement error of the rotation speed is less than± 0.1%FSR ± 1 digit
Structure Features and Safety Protection Function:
A. Indirect dry cooling gap structure: To prevent rotors from being corroded by water and negative influence on measurement accuracy caused by friction between cooling water and rotor.
B. Unique drum type rotor disk: Effectively lower rotor rotating inertia.
C. Reliable thin oil lubrication system: To guarantee sufficient lubrication and cooling of high-speed bearings and prolong dynamometer service life.
D. Perfect safety alarm devices: Including speed alarm, emergency stop alarm, inlet water pressure alarm, outlet water temperature alarm, ring over-temperature alarm, insufficient lubrication oil alarm, over-speed alarm, etc, which adequately protect dynamometer.

Nowadays CAMA eddy current dynamometers hold over 85% market share in China, products are exported to America, Australia, Russia, Turkey, Malaysia, Vietnam, Laos, etc. About 5, 000 sets of CAMA eddy current dynos are running in CAMA's more than 800 customers' company.
The main product include eddy current dynamometer, AC dynamometer, various auxiliary conditioning systems, and high-integration containerized test cells for engine, automobile parts and powertrain testing.
CAMA (originally named Nanfeng) established professional production line of dynamometer in 1987. With the introduction of dynamic balancer of Germany SHENKE company, we have processed of direct current high-power test-beds, multi-types test-beds of engine performance and complete sets of debugging and testing equipments of eddy current dynamometers. Now it has volume production capability in line with military industry quality certification system. The project passed technology authentication from ministry at the beginning of 1988 and got approval from nation at the end of 1988. In Nov. 1990, the productions were checked and accepted by experts coming from the ZOLLNER German, they considered NF productions accord with professional ZOLLNER technical specification and agreed to sell our products with NANFENG-ZOLLNER federal brand at international and civil markets. Our productions passed GB/T19001 quality system certification in 1997 and got the CMC production license of dynamometer.
CAMA the only one eddy current dynamoameter manufacturer in the world that can compare with and same to that of AVL, because two companies' eddy current dynamometer technology were same introduced from Germany Zollner.
