Mitigating EMI Issues In Servo Motors and Variable Frequency Drives

Servo motors and variable frequency drives are wide-spread in the industry. Industrial automation cannot be imagined without these motors. This article deals with certain EMI-related issues inherent to these motors, specifically high-frequency drive signals. Controller receives power from AC mains. Servo motors have a feedback circuit that allows it to maintain specific position with high accuracy. This also means that servo motors work even when they are not moving. Variable frequency drives VFD work in a different way — their speed is controlled by the frequency of the drive signal.

Servo Drive System vs. Variable Frequency Drive

Now many have passed frequency mathematical model. The stator field UVW three-phase AC motor is converted to control the motor speed and torque of the two components of the current. Torque control can be performed most famous brands are now using this drive torque control mode.

Since the 21st century, with the rise of Industry 4. Then, the author will be the following some aspects to compare. Please forgive me if there is a incomprehensive explanation. The frequency inverter can drive the variable frequency motor and the common AC motor, it mainly acts as a regulator of motor speed.

Global Field Networks Option cards and option units for communications provide support for all major field networks. Easily connect to hosts and PLCs, reduce wiring, and implement centralized management of production equipment. Single-phase motors cannot be used. The rated output current of the drive output amps should be equal to or greater than the motor rated current. Increasing the carrier frequency requires a reduction in current. This may vary depending on the motor. Rated output capacity is calculated with a rated output voltage of V.

A VFD variable frequency drive is generally used to control a squirrel cage type motor, where both stator and rotor are of a wound type to create the magnetic flux. Servo drives are used to control permanent magnet motors. Permanent magnet motor because they use rare earth magnets in the rotor, create a much higher magnetic flux for their given size. This enables the motor to be able to create more torque in a much smaller rotor and hence motor size. Giving the motor a lower inertia to accelerate and decelerate much more dynamically than that of the asynchronous squirrel cage type motor.
