Applications
SMDM series dynamometer is a kind of special test equipment with
low speed and high torque. The main task is to load the low-speed
and high torque machinery. The dynamometer also has the function of
driving the specimen.
Its main purpose is to test the dynamic performance of commercial
vehicle motor, high torque motor, diesel engine and axle. These
samples have the characteristics of high torque output at low
speed. SMHC realizes the accurate control of speed and torque
through an efficient inverter system, and all test operations can
be completed by computer control commands. At the same time, the
high-speed data communication module makes the system have high
real-time performance. SMDM series dynamometer has the
characteristics of small volume, small moment of inertia, high
torque output at low speed and high dynamic response.
Benefits at a Glance
- It can be used as loading equipment and prime mover. It can drive
and absorb power in both directions of rotation.
- Measurement accuracy: speed ± 0.1 R / min; torque ± 0.2% FS
- Overload capacity: 150% overtorque ≥ 10min, 200% overtorque ≥ 1min
- At zero speed, the full load can be added, and the speed can be
reduced to zero without torque attenuation, which can reach twice
the full load in a short time.
- Excellent loading performance: constant torque loading can be
maintained from zero speed to rated speed, and constant power
loading can be maintained above rated speed.
- Low moment of inertia and high overload capacity make the
dynamometer have high dynamic response speed, the dynamic response
speed is less than 5ms
