Motor dynamometer, transient dynamometer
Test applications for motor dynamometer cover automotive production and development, aviation, aerospace, military and scientific research. DynoEquip provides electric motor dyno testing for aerospace and aircraft motor, permanent magnet synchronous motor and automotive high speed electric motor, also for industrial electric tools, home appliances, starter, fan, electric pump, blower and traction motor.
Motor dynamometer performance testing requires benchmark of motor performance at various temperatures and loads. The durability test of electric motor ensures that the motor is designed for the calculated usage time period to simulate long-term motor service life. The simpliest motor test method is to withstand different loads and maintain the relatively constant speed. There are also motor that needs to be tested in varying torque and speed environments to understand the motor load effects.
DynoEquip are striving to enable customers for electric motor and powertrain product development with the requirements of quick, effective manner and good price. With using DynoEquip dynamometer and our strong engineering capabilities, we support customers on product improvement in regard to functionality, durability, reliability and quality.

Portable EMC chassis dynamometer
DynoEquip portable chassis dynamometer is constructed as a freestanding dynamometer, which can be fixed onto a turntable or a stand-alone system. Two active elements are used for cars with rear or front wheel drive. Each car wheel is driven by a separate motor or generator. It can be used for acceleration or retardation and in an endurance mode. The free-standing dynamometer is prepared to be used in an anechoic chamber for EMI and EMC measurements. All electronic components are located in a separate box, which is shielded, and radio interference suppressed.
Aviation simulation dynamometer
DynoEquip aircraft starter generator test system provides high-precision, three-phase monitoring of electrical power in and out of the starter-generator, as well as accurately measuring torque, speed, and mechanical power in or out of the unit. DynoEquip can effectively test all aspects of this product in both operating modes with a single test system. The regenerative design allows the test system to simulate the engine, as a load, during the start phase, as well as the main driver during the generation phase of operation. It also allows for recapture of absorbed power. This significantly improves system efficiency and reduces power consumption and overall testing costs.
