This paper proposes a new feedback-type dead-time compensation method. The proposed method compensates the output voltage by employing two operations. First, the normal compensation matches the width of the output pulse to that of the input pulse with reduced delay time from the input pulse to the output pulse compared with the conventional method. Second, the short pulse compensation generates an output pulse after a few pulses are input so that the average value of the output signal equals that of the input signal. The voltage utilization factor of the proposed method is almost 100%, because there is no limit to the compensation and the decrease in the fundamental output caused by dead time is eliminated. The experimental results using a 100-kHz input signal show that there is no discrepancy between the output pulse width and the input pulse width. Furthermore, the THD of the compensated output current, when the output frequency is 50Hz, is eliminated, compared with that of the output current without compensation. These results show that the proposed method has low distortion and high voltage utilization factor characteristics.

This paper proposes simulation methods based on the forward Euler method that are suitable for real-time simulators. However, real-time simulation using the forward Euler method has the following problems: A simulation error caused by a time step limitation and a delay in the simulated waveforms. The authors have proposed a simulation method suitable for real-time simulators, but the physical meaning of the state variables is diluted by diagonalization of the system matrix. This paper proposes a simulation method to obtain the same characteristics as the previous method, without diagonalization. Off-line and real-time simulation results demonstrate the validity and usefulness of the proposed simulation method.

A bearingless motor is characterized by integration of an electrical motor and a magnetic bearing. Electromagnetic force generated by the magnetic bearing function can realize magnetic suspension of a rotor shaft without mechanical contacts. Principal authors have been proposing a non-contact canned motor pump using the bearingless motor. This pump has no expendable parts, such as shaft seals, mechanical bearings and lubricant. Therefore, it can realize next advantages; 1. clean liquid sending. 2. maintenance free 3. longer operating life. 4. high chemical resistance. The previous paper has proposed novel structure which can generate high output and high suspension force compared with conventional structure. A prototype bearingless canned motor pump with the proposed high power structure is produced, and characteristics of suspension force and torque is tested in the prototype machine. This paper introduces the experimental results of the prototype machine with the proposed high power structure in detail.

Permanent magnets made of rare earth materials are used in interior permanent magnet synchronous motors (IPMSMs), which are major component of hybrid electric vehicles. The recent remarkable increase in the cost of rare earth materials is a major concern. A switched reluctance motor (SRM) without permanent magnets is one of the possible alternatives. Two types of SRMs have been designed with different materials. The SRMs have been investigated full loading tests. This paper reports a comparison between experimental and analysis results for the SRMs. The efficiency of both SRMs can exceed 90%, and the output power can be in excess of 50kW.

A wide magnetic gap consequent-pole type bearingless motor has been developed. The wide magnetic gap makes it difficult to start up and suspend a shaft with reasonable suspension voltage and current. To provide high current, high voltage rating is demanded, although, high voltage causes bad influence on magnetic suspension. In this paper, the authors have investigated the start-up and rotational characteristics of a prototype bearingless machine driven by voltage source inverters having the rated voltage of 200V and 100V. When the rated voltage is not suitable, significant problems are occurred. The effectiveness of proper selection in the rated voltage is discussed. The result of this study shows that the 100V inverter is a better choice for the bearingless motor.
