Dynaspede meets the testing needs of automotive, aerospace, academic and industry sectors with a wide range of dynamometers and application-specific test benches. The offerings are backed by experienced sales and service teams from multiple locations for effective application and service support.

In a strategic alliance with Froude Hofmann, world’s leading specialist-suppliers of engine and vehicle testing solutions, Dynaspede brings you the widest variety and range of dynamometers under a single roof. These would cater to virtually all the testing needs of driving and driven elements for performance verification or design validation of prime movers, actuators and transmissions. From the tiny eddy current dynamometers and high torque-low speed powder dynamometers through precise low inertia AC dynamometers, portable and rugged Go-power range and big multi-megawatt units, all are offered with dedicated controllers, data acquisition hardware and comprehensive software for diverse application requirements.

Eddy Current Dynamometers

The medium of torque transmission in Eddy Current dynamometers is a controlled magnetic field generated by a stationery coil. The developed torque in these dynamometers diminishes with reduction in speed with no torque developed at zero speed. These dynamometers are ideal for testing engines and motors in the medium to high-speed range and machines with turbo characteristics.

Features:

• Torque ratings: 0.2 Nm to 4500 Nm
• Power absorption: 20 W to 750 kW
• Speeds: Up to 30,000 rpm depending on the model
• Compact, high torque-to-inertia ratio

Magnetic Particle (Powder) Dynamometers

Powder dynamometers develop torque on the basis of electro-mechanical principles wherein the torque developed is independent of speed.Here the braking torque is infinitely adjustable through themedium of fine magnetic powder under the influence of the controlled magnetic field. These dynamometers are ideal for testing motors from zero speed, transmissions and machines demanding high torque at low speeds.

Features:

• Torque ratings: 2.5 Nm to 600 Nm
• Power absorption: 250 W to 24 kW
• Speed: Up to 4000 rpm depending on the model
• Set torque: Stable right down to zero speed
• Compact, high torque-to-inertia ratio

AC Dynamometers

The energy-efficient AC dynamometers are highly versatile and can operate in both motoring and absorption modes. These dynamometers are ideal for transient studies and for loading from true no-load to stall conditions.

Features:

• Energy-efficient
• Fast response and high degree of control stability
• Direct measurement of friction / system losses
• Ratings up to 750 kW
• Inertia and vehicle road-load pattern simulation
• Trunnion mounted or with in-line torque sensor
  

Hydraulic Dynamometers

Hydraulic dynamometers are available in a wide range from portable Go-Power series to robust HS range of high-speed models, meeting the demands of automotive industry, industrial diesel engines, marine and gas turbine applications.

Features:

• Ratings of 750 kW to 50 MW
• Servo load control
• Rapid response
• Stable operation
• High reliability
• Easy maintenance

Tandem Dynamometers

Hybrid Dynamometers, also known as Tandem Dynamometers, are combinations of any two forms of dynamometers described above. A judicious selection and sizing of units provide a combination with extended speed and power ranges as needed for load testing of hydraulic motors, servo motors and so on. Gradual and bump less changeover is ensured by a PLC or PC based control system tailored for individual applications.
