Dynamometer Test Bench Composition Description
The overall test bench is shown in the figure above, which mainly
includes a electric dynamometer, a mounting bracket for the motor
under test, a connecting shaft, a protective cover, etc.
The electric dynamometer contains an air cooling device (fan), a
rotary encoder and a shaft temperature monitoring system. The motor
bearings are imported bearings; the speed signal is sent to the
variable frequency drive cabinet through the bus, and the torque
signal is sent to the control system using the original shielded
cable to form Closed-loop control. At the same time, the speed and
torque values are stored, displayed, and adjusted and controlled in
the computer unit.
Application
The Seelong E-Motor test beds are used for analyzing and
determining electrical, mechanical, thermal and acoustic
properties. Functionality, reliability and durability tests and
cold start performance measurements can be implemented under
realistic conditions. The integrated Seelong TCM automation system
allows for fully automatic runs, so time and cost-efficient test
ones for all relevant test procedures.
All measurement data is saved with a uniform time stamp and can be
processed further with the data post processing tool, The optional
integration of the "Virtual Proving Ground" technology based on
SeeLong SLM also offers a virtual development and test environment
to implement integration, optimization and validation tasks even on
the test bed.

SSCH45 electric dynamometer has the following significant advantages:
The basic principle of Hydraulic and eddy current dynamometer is to
convert the mechanical energy generated by the prime mover into
heat energy and take away the heat after cooling by water. The
energy emitted by the prime mover cannot be recovered, and energy
is also consumed during the conversion process. However, the
electric dynamometer can convert the mechanical energy generated by
the prime mover into electrical energy and feed it back to the
internal grid for use by other equipment.
The loading characteristics of the electric dynamometers are
constant torque characteristics from zero speed to rated speed, and
constant power characteristics from rated speed to maximum speed,
which fully comply with the load characteristics of power
machinery. Generally, the hydraulic dynamometer can only be loaded
in one direction, while an eddy current dynamometer can be loaded
in two directions, it cannot be used as a power back-drag prime
mover, while the electric dynamometer can easily realize two-way
loading and can be used as a power back-drag prime mover.
Due to the use of accessories that fully comply with national
standards, users do not have to rely on the manufacturer for
maintenance, and can completely carry out daily maintenance by
themselves, even when it is necessary to replace the host and
sensors. The electric dynamometer is the most ideal replacement
product for the technological transformation of enterprise testing
equipment due to its simple structure and maintenance-free, in
addition to its excellent speed control performance, it also has a
significant energy-saving effect.
The electric dynamometer is the test core of the whole test bench
system. It adopts the variable frequency inverter system as the
actuator of the electric dynamometer and adopts Seelong’s new
generation test and control system as the control core of the test
bench system. Seelong software test system is developed based on C#
platform and can carry out high dynamic control of the system.
Seelong test and control system can automatically complete the
relevant setting test cycle and user-defined dynamic test cycle; At
the same time, Seelong test and control system can integrate
external auxiliary equipment, perform centralized communication and
control.
Seelong's test bench system adopts modular design, according to
different test requirements and budgets, our professional engineers
will customize different dynamometer test bench systems for
customers.
Let’s become partners, we will provide lifetime free software
system upgrade for our dynamometer test bench system (Excluding the
development of new applications).
Typical application
1) Research on motor performance test and control
2) Motor efficiency evaluation
3) Feed performance evaluation of motor system
4) Motor durability assessment, etc.
