VFD Motor Control Overview
A three phase asynchronous motor converts electrical energy into mechanical power and can also function as a generator at the same time. The rated speed of the motor is determined by the number of pole pairs. 4-pole motors are the most frequently used type (1500 rpm at 50 Hz), but 2 and 6-pole motors are also sometimes encountered. A magnetizing current needs to start flowing when the motor is in the idle state so that a magnetic field can be generated. As soon as the motor goes on load, the motor speed drops in relation to the no-load speed. An AC Tech VFD can be used to compensate for this phenomenon, which is termed slip, via its control function, e.g. VFD vector control. If the rated speed is exceeded, operation can continue but will be subject to reduced torque (field weakening range). The basic dimensions of the motor, such as the shaft diameter, flange diameter and foot height, are standardized. Various built-on accessories (e.g. brake, encoder, blower) can be used to adapt the motor 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 Tech prefers to focus on VFD solutions which have been specifically designed for handling and materials handling technology, for all types of automotive engineering process, for robotics, for a wide range of packaging machines and for many other applications. AC Tech VFD solutions are the key to implementing innovative machine and system concepts quickly and successfully in the interests of increased productivity. AC Tech’s powerful and highly reliable VFD products are based on established standards and are very user-friendly.
