Almost 70% of the energy produced by the generator is consumed by electric motors. The use of induction motors in industry and factories is more profitable than DC or synchronous motors, one of the advantages is easy maintenance and high efficiency. On machines in the industry speed regulation is absolutely necessary. Along with the development of power electronics, this has become very easy to do, namely by supplying a motor with a variable speed drive (VSD) inverter. With the supply of a variable speed drive inverter, it is possible to adjust the motor speed by adjusting the voltage frequency.This study was conducted to determine the effect of decreasing the frequency using a variable speed drive inverter on the performance of a five-phase induction motor. Tests are carried out at a frequency of 50 Hz (grid frequency), 35, 40, 45, 50 Hz (inverter frequency) and the motor is loaded at 0.5, 1, 1.5, 2, 2.5Nm. From the research, it was concluded that, among others, the use of a variable speed drive inverter resulted in greater motor losses and the motor produced a louder sound. At the same frequency (50 Hz) the efficiency of the motor is better when supplied directly from the grid.

DC brushless motors are widely adopted for their simplicity of control, even in sensorless configuration, and their high torque density. On the other hand, induction motors are very economical due to the absence of permanent magnets; for the same reason they can easily be driven in the flux-weakening region to attain a wide speed range. Nevertheless, high dynamic induction motors drives, based on field-oriented (FOC) or predictive control, require large amounts of computing power and are rather sensitive to motor parameter variations. This paper presents a simple DTC induction motor control algorithm based on a well-known BLDC control technique, which allows to realize a high dynamic induction motor speed control with wide speed range. The firmware implementation is very compact and occupies a low amount of program memory, comparable to volt-per-Hertz- (V/f-) based control algorithms. The novel control algorithm presents also good performance and low current ripple and can be implemented on a low-cost motion control DSP without resorting to high-frequency PWM.

Abstract— An induction motors  (IM) in many industries is used because it has several advantages, such as a very simple and strong construction, the price is relatively cheap, has good efficiency, power factor is quite good, and maintenance is easier. Besides the advantages of induction motors also have disadvantages, one disadvantage of induction motors is not being able to maintain a constant speed when there is a change in load. If the load changes, the speed of the induction motor will decrease. One method of regulating the speed of an induction motor presented in this study is the regulation of an induction motor using a carrier based PWM (CBPWM) inverter with the field oriented control  (FOC) technique. The estimation of rotor rotation, torque and flux is done by carrier- based PWM  technique which is given input voltage and stator current. To achieve the desired flux and torque, estimation is used as feedback in the control system. In this study, it will be simulated the induction motor speed regulation with a carrier base-based inverter using Matlab. The results obtained through simulation show the length of time to reach the reference speed for speeds of 1500 rpm and 1450 rpm is around 0.45 seconds. And THD  average 2,675%.

Metal sorting conveyor is a device that is used to separate metal and non-metal objects, the drive of this conveyor uses ½ Horse Power (HP) induction motor as its prime mover. To adjust the rotation of the induction motor 1 HP Variable Frequency Drive (VFD) is used. This VFD is set with the double speed parameter so that later the motor can rotate variably in two speeds. The input parameters of the VFD itself use switches in the form of photo electric and inductive proximity which are controlled automatically using Programmable Logic Control (PLC). The digital output of the PLC will then communicate with the digital input of the VFD so that when the object on the conveyor is detected by a photoelectric, the VFD will adjust the frequency by 8,5 Hz, if the object on the conveyor is detected by metal by inductive proximity, the VFD will set the frequency by 14,5Hz . So that at each of these frequencies the motor can rotate with speeds of 241,5 rpm and 359,5 rpm. The results of the trials carried out show that VFD can regulate in a number of speeds in a variable manner, but in this study limited to using two speeds or double speed as a variable speed experiment.

Cascaded Multilevel Inverter

Currently, induction motors are widely used in industry because have a high potential for the efficiency improvement. Therefore, a topic of interest to the industry is to reduce the energy consumption of induction motors, as they represent almost half of the total electrical energy consumption in the world. The energy consumption of electric motors can be reduced by using motors that are more efficient and by using power converters to feed the motors, thereby enabling accurate control according to the load. The function of the power converter is to modify the intrinsic characteristics of the induction motor (speed and torque). There are different topologies of the power converter commonly called inverter for induction motors. An inverter requires a modulation strategy for its operation, there are several modulation strategies that are used in the induction converter-motor assembly. This paper presents the comparative analysis of the influence of the phase disposition modulation (PD-PWM) strategy with different modulation indices, on parameters related to the output signal of a seven-level cascaded multilevel inverter as well as on the nominal working conditions of a three-phase induction motor.

Data acquisition systems have been used for many years in order to conduct analyses to increase efficiency, measure performance and detect failures in electrical motors.High costs and not being of modular use have prevented these systems from being commonly used. Various methods were developed for data acquisition from electrical machines. This paper presents data acquisition analysing and monitoring system using Arduino platform. Vibration, temperature and current values of a 3 phase induction motor are obtained by this data acquisition system via USB port. A system compatiable with all sorts of settings and of low cost was obtained as a result of using Arduino where data processing is conducted on a computer. Values obtained from the data collection system used in this study were found to be supportive to the values shown by the measurement devices from 3 phase induction motor.
