The motor test bench is an indispensable and important equipment in motor manufacturing and production. It is also directly related to the comprehensive evaluation of the assembly quality and technical performance of the motor. With the development of technology, traditional testing equipment and methods are no longer able to meet the increasing demand for testing. The emergence of motor test benches has greatly improved the efficiency, accuracy, and quality of motor testing.
The motor test bench is fully automated, computerized, and efficient, with safety features designed to prevent misoperation. It adopts an English interface operation, automatically collects and calculates measurement data, generates and prints factory test reports. The measurement control system adopts PLC programming control, which is particularly suitable for occasions with high product requirements and batch testing. The emergence of motor test benches has effectively improved the efficiency and accuracy of motor testing, which is of great significance for motor research, production, and maintenance.
The motor test bench adopts advanced virtual instrument technology, combined with the powerful computing power of computers and the measurement and control functions of hardware equipment, to achieve automated control and data processing of experiments through software. This system has functions far beyond the simple combination of general instruments, especially in terms of result saving, waveform storage, synchronous measurement, test report generation, as well as system scalability and multifunctionality, reflecting advantages that traditional manual test benches do not possess.
The efficiency and accuracy of the motor test bench are indispensable technical equipment in the development of the motor industry. It not only meets the high standard requirements for motor performance and quality indicators, but also promotes the continuous innovation and development of motor testing technology. The widespread application of motor test benches provides solid technical support for the continuous progress of the motor industry.
Purpose of motor test bench
The motor test bench can be used to check motor current, voltage, torque, speed, temperature, etc. It adopts bus feedback type variable frequency feedback loading, and does not pollute the power grid during energy feedback. Ensure that the energy absorbed by the loading motor is fed back to the driving motor, with an energy conversion efficiency of ≥ 75%. The loader has a constant torque operation function and can fully meet the requirements of loading tests through computer interfaces and software.
The control system of the motor test bench is divided into two operating modes: manual control and automatic control, and can be easily and freely switched. The test bench can implement program loading, arbitrarily set the input speed, torque, operating time, automatic recording time and other parameters of the motor within a limited range, automatically complete the entire test process according to the set test program, and monitor and record the test data and graphics in real time, as well as various safety monitoring alarms. When the program-controlled automatic shutdown test equipment is turned off, all power sources of the test equipment are disconnected except for the industrial computer.
The motor test bench has a complete internal status display, making the system operation status transparent; It also has complete fault self diagnosis capability, automatically detects fault points, and helps maintenance personnel to timely and accurately locate fault points; It should also have the functions of interlocking alarm and interlocking shutdown.
