PERFECT ELECTRICAL GENERATORS AND GENERATING SETS. Brushless, multiphase, high degree self-invariance of output frequency, incomparably HIGH OPEN-LOOP GAIN, MUTUALLY-INDEPENDENT THREE-CHANEL DIRECT CONTROL of output VECTOR'S THREE MAIN COMPONENTS-frequency, voltage and phase. Low control power. High reliability. Setting of output frequency by single pulse injection. Autonomous Generating Sets. Wind - Electrical Plants. Electric Power Stations. Adapter (Coupler) in Power Grids and independent active and reactive exchange power control. Ease of CNC. Low price and service expenses.
PERFECT SYNCHRONOUS MOTOR. Brushless, multiphase, fed from SUPPLY DIRECTLY, SHORT-CIRCUITED (casted) ROTOR, EFFECTIVE and FULL AUTO-START (SELF-START) and PERFECT SELF-REGULATION ( internal self-adaptation) of MOTOR TORQUE in synchronous speed;self-forcing under load; NO SEMICONDUCTORS & ELECTRONICS inside and outside the motor; NO PERMANENT MAGNETS; NO CONTROL SYSTEMS OR APPARATUS at all for the motor control in starting and in forcing. JUST SWITCH the motor ON and FORGET IT.
PERFECT INDUCTION MOTOR. Brushless, anyphase, ESSENTIALLY HIGH ALL TECHNICAL-and-ECONOMIC INDEXES: incomparably low starting and no load currents, high starting torque, high power factor, high efficiency, low rated slip, low ratio of current to torque, LOW METAL CONSUMPTION. If instead of a traditional known induction motor in the modern frequency controlled drives you use this proposed induction motor only, you will get another drive with incomparably high levels of energetics and of static and dynamic indexes of motion control under very low price.
PERFECT ELECTRIC DRIVES. Frequency controlled DRIVES with the above (points 2 and 3) motors, having MUCH MORE SIMPLE control system STRUCTURE and CONTROL FUNCTION, and PROVIDING SYSTEM’S HIGH STATIC and DYNAMIC INDEXES-WITHOUT control function continuous synthesing. Low price and service expenses, simple and fast adjustment and tuning, unified structure.
VECTOR CONTROL HIGH TECHNOLOGIES. New highly-effective vector control algorithms, technique and soft-ware in electronic controlling and CNC of frequency contolled AC motor drives with ordinary and preferably with the above (point 3) induction motors.This is a quite NEW APPROACH or in some sense it is a virtual strategy for frequency controlling of induction motor drives, which is based on the created NEW PHYSICAL PRINCIPLE, providing very high energetic and control quality static and dynamic indexes under very low price. Large range of speed and torque control, positioning. High energetics and control quality indexes. PERFECT PERFORMANCE OF VECTOR CONTROL AT LOW (ZERO) SPEED REGION. New electromagnetic optimal control high technologies in motoring and in imitative regenerating. High algorithmic technologies for effective control of motor electromagnetic transients and torque in static and dynamic modes. Controlled and Minimized ratio of current to torque under any speed. Sensorless control is available.
