VFD Motor Control Overview
A three phase asynchronous motor convertselectrical energy into mechanicalpower and can also function as a generatorat the same time. The rated speed ofthe motor is determined by the numberof pole pairs. 4-pole motors are the mostfrequently used type (1500 rpm at50 Hz), but 2 and 6-pole motors are alsosometimes encountered.A magnetizing current needs to startflowing when the motor is in the idlestate so that a magnetic field can begenerated. As soon as the motor goes on load,the motor speed drops in relation tothe no-load speed. An AC Tech VFD can be used to compensate for this phenomenon,which is termed slip, via itscontrol function, e.g. VFD vector control.If the rated speed is exceeded,operation can continue but will be subjectto reduced torque (field weakeningrange).The basic dimensions of the motor,such as the shaft diameter, flange diameterand foot height, are standardized.Various built-on accessories (e.g. brake,encoder, blower) can be used to adapt themotor to suit the relevant VFD task.
AC Tech VFD Solutions
AC Tech VFD products are used for electronic speed control of AC induction motors. The needs of the market are wide and varied, and AC Tech VFD solutions offer a broad range of standard products for everything from simple speed control to complex; each with a wide range of functionality, small physical size and exceptional performance. AC Tech VFD solutions are flexible to apply, easy to commission, and meet the highest standards of quality. AC Tech VFD products provide solutions to fulfill nearly any VFD requirement in the power range between 0.25 and 400 kW.
Rather than dealing with individual VFD applications, AC Techprefers to focus on VFD solutionswhich have been specifically designedfor handling and materials handlingtechnology, for all types of automotiveengineering process, for robotics, for awide range of packaging machines and formany other applications. AC Tech VFD solutionsare the key to implementing innovativemachine and system concepts quickly andsuccessfully in the interests of increasedproductivity. AC Tech’spowerful and highly reliable VFDproducts are based on establishedstandards and are very user-friendly.
