“…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>

Additional High-Frequency Signal for Sensorless Angular Positioning of the Rotor in Synchronous Motors

This is a feasibility test for sensorless angular rotor positioning. The paper analyzes the existing methods for sensorless control of angular rotor position in AC motors. It identifies their common drawbacks, one of which is that angular rotor position is difficult to determine at low or zero rotor speed unless a mechanical sensor is in use. The paper presents the functional diagram of a sensorless electric drive based on a synchronous motor. It considers the correlation of induced EMF and high-frequency voltage signal fed to the SM excitation winding. The paper further derives a formula to describe the angular rotor position as a function of phase EMF. The derivation is based on Park-Gorev equations. The obtained dependencies are used in an implemented structural diagram, with the research output being discussed in detail.
