They allow for precise and flexible control of speed, torque, position and direction of the motor and the load. They also improve the efficiency and reliability of the system, reducing energy consumption and wear and tear. They can also adapt to different types of motors, loads and applications, such as pumps, fans, conveyors, cranes, robots, etc.
However, accionamientos electricos also have some drawbacks and challenges. They require complex and expensive electronic components and circuits that can be affected by environmental factors such as temperature, humidity, dust and vibration. They also generate harmonic distortion and electromagnetic interference that can affect the power quality and the performance of other devices. They may also need additional protection and cooling systems to ensure their proper operation and safety.
Therefore, it is important to choose the right type of accionamiento electrico for each application, considering the characteristics and requirements of the motor, the load and the system. There are different types of accionamientos electricos depending on the type of motor they control (AC or DC), the type of converter they use (rectifier, inverter or chopper), the type of control they implement (scalar or vector) and the type of feedback they receive (open loop or closed loop).One of the main aspects that differentiate accionamientos electricos is the type of control they implement. Control is the process of adjusting the output voltage and frequency of the converter to achieve the desired speed and torque of the motor. There are two main types of control: scalar and vector.
Scalar control, also known as V/f control, is the simplest and most common type of control. It is based on the principle that the ratio between the voltage and the frequency applied to the motor should be constant to maintain a constant flux in the stator. Scalar control does not require any feedback from the motor or the load, and it can be easily implemented with a simple algorithm. However, scalar control has some limitations, such as poor dynamic performance, low accuracy and efficiency, and inability to provide full torque at low speeds.
Vector control, also known as field-oriented control, is a more advanced and sophisticated type of control. It is based on the principle that the stator current of the motor can be decomposed into two components: a torque component and a flux component. Vector control uses feedback from sensors or estimators to measure or calculate these components and adjust them independently to achieve optimal speed and torque control. Vector control can provide high dynamic performance, accuracy and efficiency, and full torque at low speeds. However, vector control requires complex and expensive hardware and software, and it may need additional tuning and calibration. a474f39169
