Product Description

Product description

 

The host of the electric dynamometer adopts a dedicated AC permanent magnet synchronous servo motor, and the electric dynamometer is equipped with a torque measurement device and a speed measurement device for torque and speed measurement.
The electric dynamometer includes an air cooling device (fan), a rotary encoder and a shaft temperature monitoring system. The motor bearings are imported; 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 a closed-loop control. At the same time, the speed and torque values are stored, displayed, and adjusted and controlled in the computer unit.

Drive motor features

 

Seelong medium and low inertia servo motor is AC permanent magnet synchronous servo motor, which has the following excellent characteristics and provides reliable guarantee for customers' industrial robots and high-end intelligent equipment:

 

1) Industry-leading magnetic circuit design and simulation. It can achieve high torque density, very low cogging torque and high overload capacity. Compact structure is suitable for all kinds of occasions with high requirements on installation size;
 

2) Customizable winding design. The rated speed can be up to 10000 rpm, Seelong servo motor provides more than 200 standard winding designs, and can customize winding speed according to users' needs to meet various demanding application requirements.
 

3) Excellent heat dissipation ability and perfect temperature protection. High-grade heat-conducting potting compound is used in the servo motor to provide high insulation characteristics, which greatly enhance the heat dissipation capacity of the motor.
 

4) Three kinds of winding temperature sensors which are selectable by users ensure that the motor can be perfectly protected at any time; The protection level is up to IP66. Adopting shaft seal, make the protection level of servo motor reach IP66 -Completely dust proof and protecting against strong water spraying;
 

5) Highly reliable connectors and prefabricated cables. The cable connector imported from Germany is durable and rotatable. Prefabricated cables have excellent performance, conventional and highly flexible cables are available;
 

6) High precision feedback encoder. Seelong servo single motor can be equipped with a variety of encoder types, including single/multi-turn absolute value, resolver and incremental type, the highest accuracy can reach 12bit for multi-turn and 25bit for single turn;
 

7) Single connector design (optional configuration) combines the power cable and feedback cable of servo motor into one.

 

Electric dynamometer has the following significant advantages:

• Energy saving

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.

• Loading features

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.

• Maintainability

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.

• Openness

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.

• Modular design

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).
