“…When this voltage equals the maximum possible voltage from the drive electronics, then no more current can flow into the motor and torque falls to zero. This provides a practical upper bound on motor speed and torque at high speeds [23]- [25]. Accordingly, the developed model of the electric drive can be used to perform welding operations.…”

<p>In recent years, there has been a great interest in the transition to digital and automation services for dangerous and menial working processes. Due to its MH50-35 industrial robot, Motoman's properties allow us to improve the control system of an electric drive for industrial robots. The structure of the electric drive for six-axis robot manipulator performance can be superior to conventional Drive Control servos for motor excitation, and a novel automation system can be implemented for its servo performance. To solve these issues, we propose an optimization strategy that allows us to achieve an increase in productivity and labor safety in the industry, reduce the percentage of defects, guarantee product uniformity, and reduce the prime cost of production of items. Ideal conditions were anticipated using a mathematical model. In this study, by using a statistical model, the ideal conditions were synthesized. The optimization of the control system of an electric drive for industrial robot analysis was carried out, and our findings suggest using this model in industrial production to elucidate problems such as high accuracy and speed indicators.</p>

“…The expression of the coefficient γ will be given in Equation (5). Since the electromagnetic torques given by two electric machines are not only used to accelerate the vehicle body, but also all of the rotation components (including rotors of electric machines, gear groups, and wheels), the coefficient γ can be understood as a ratio to convert both linear and rotation masses into one linear mass.…”

“…In offline simulation, the time limit on calculating the target system model is relatively low, because only the logic and feasibility of the new function need to be studied in this step [3]. On the contrary, real-time simulation aims at testing the maneuverability and effectiveness of the new function, and it is commonly used in hardware-in-the-loop (HIL) testing [4,5]. During HIL testing, it is of particular importance to coordinate the frequency of the function control signals and the real-time model simulation time-step [6].…”

Real-time simulations refer to the simulations of a physical system where model equations for one time-step are solved within the same time period as in reality. An FPGA/CPU-based real-time simulation platform is presented in this paper, with a full-electric vehicle model implemented in a central processing unit (CPU) board and an electric drive model implemented in a field programmable gate arrays (FPGA) board. It has been a challenge to interface two models solved with two different processors. In this paper, one open-loop and three closed-loop interfaces are proposed. Real-time simulation results show that the best method is to transmit electric machine speed from the vehicle model to the electric derive model, with feedback electric machine torque calculated in FPGA. In addition, a virtual vehicle testing tool (CarMaker) is used when building the vehicle model, achieving more accurate modeling of vehicle subsystems. The presented platform can be used to verify advanced vehicle control functions during hardware-in-the-loop (HIL) testing. Vehicle anti-slip control is used as an example here. Finally, experiments were performed by connecting the real-time platform with a back-to-back electric machine test bench. Results of torque, rotor speed, and d&q axis currents are all in good agreement between simulations and experiments.

Electrical Platform for Drive of Ac Asynchronous Motors and Servomotors Using Frequency Converters

The development of industrial automation has implicitly led to the improvement of electric drive systems, especially since such installations are the most common form of conversion of electricity into mechanical energy. The electric drive can be defined and studied only if we consider the whole assembly of which it is part, such as the automation of a technological production process. This paper describes the design and practical implementation of a laboratory stand with a teaching feature. The designed stand is a study support for various applications used in the industrial area, offering the possibility of experimentation on programming and parameterization of frequency converters in the laboratory of "Electrical machines and drives" of the Faculty of Electrical Engineering, Electronics and Information Technology at the University of Valahia from Targoviste.
