The paper addresses modelling of a two-phase induction motor. Based on geometric dimensions, the model was created in the 2D and 3D ANSYS Maxwell program. Transient process at the motor start-up was calculated within the same program, too. Another model was made up based on the induction motor mathematical description in the MATLAB/Simulink program. Waveforms of the motor currents and torques are compared. Models created in MATLAB/Simulink and ANSYS are compared with measurements. For measurements was used a symmetrical two phase power supply.

This paper describes the control of two-phase induction motor using a conventional three-phase bridge inverter. Two-phase induction motors in comparison with conventional three phase motors have the advantage of a simple stator current vector control. The physical phase currents themselves represent the coordinates of the stator current vector. For this reason two-phase induction motors are ideal for educational purposes as well as for experiments verifying various control strategies (for example sensorless speed control). The inherently best inverter topology for a two-phase induction motor consists of two single-phase bridge inverters. However, using a conventional three-phase bridge inverter may be an interesting alternative described in this paper.

In this paper the design and the magneto-static simulation of axial-flux permanent- magnet stepper motor with the disc type rotor is presented. Disk motors are particularly suitable for electrical vehicles, robots, valve control, pumps, centrifuges, fans, machine tools and manufacturing. The brushless machine with axial flux and permanent magnets, also called the disc-type machine, is an interesting alternative to its cylindrical radial flux counterpart due to the disk shape, compact construction and high torque density. This paper describes a design of four phase microstepping motor with the disc type rotor. The FEM modeling and the 3D magneto-static simulation of the disk stepper motor with permanent magnets is being subject of the article, too. Disc rotor type permanent magnet stepper motor for high torque to inertia ratio is ideal for robotics and CNC machines.

The brushless machine with axial flux and permanent magnets (AFPM), also called the disc-type machine, is an interesting alternative to its cylindrical radial flux counterpart due to the disk shape, compact construction and high torque density. AFPM disk motors are particularly suitable for electrical vehicles, robots, valve control, pumps, centrifuges, fans, machine tools and manufacturing. The first parts of the paper compare of drive system with disk-motor to the motor with cylindrical shape, as well as disk-motor with radial and axial flux. Next part of the contribution describes types of the disk motors and their construction. The 3D magnetic simulation and analysis of the disk stepper motor with permanent magnets is being subject of the article, too. The unique disc-type profile of the rotor and stator of AFPM machines makes it possible to generate diverse and interchangeable designs. AFPM machines can be designed as single air gap or multiple air gaps machines, with slotted, slotless or even totally ironless armature. Low power AFPM machines are frequently designed as machines with slotless windings and permanent surface magnets.

This document deals with electromagnetic compatibility (EMC) of universal motor operating at AC and DC power supply. Universal motors are used in a variety of applications and can be operated either at AC or DC supply current. The advantages of universal motors are especially high starting torque, very compact design and high running speeds. The drawback consists in the fact that the commutator and arcing brushes create electromagnetic interference (EMI), ozone and noise. This paper presents the results of oscilloscopic measurement of disturbing magnetic field in proximity of a universal motor at various speeds at AC and DC operation mode. The time derivation of the magnetic flux density is converted by an inductive coil to a voltage to be observed by oscilloscope.

Universal motors are usually operated in AC mode and are controlled by means of triacs. This conventional solution is characterized by a cheap control hardware. On the other hand, it has some drawbacks. In particular the high peak to peak current gives poor motor efficiency and the consequential high brush temperature leads to limited motor lifetime. Significant improvements are obtained when using a more exacting converter. This paper presents the results obtained by using a diode rectifier and PWM controlled IGBT chopper. The RMS and peak-to-peak current of the motor are reduced, as well as electric losses and brush temperature. In addition, this operation mode enables increasing the motor output power or the motor lifetime. In order to reduce switching losses and electromagnetic interference of the converter, the assumed switching frequency is not higher than 1000 Hz.
