How can I control PMSM?

How can I control PMSM?

Vector control in a synchronous reference frame is the best way to control the permanent magnet synchronous machine (PMSM). The field-oriented control is used to control the spatial vectors of magnetic flux, stator current and voltage.

How do PMSM motors work?

A permanent-magnet synchronous motor (PMSM) uses permanent magnets embedded in the steel rotor to create a constant magnetic field. At synchronous speed the rotor poles lock to the rotating magnetic field. Permanent magnet synchronous motors are similar to brushless DC motors.

What is the acronym for PMSM in a PMSM motor?

Definition. PMSM. Permanent Magnet Synchronous Motor. PMSM. Permanent Magnet Synchronous Machine (engineering)

What is FOC control?

Vector control, also called field-oriented control (FOC), is a variable-frequency drive (VFD) control method in which the stator currents of a three-phase AC or brushless DC electric motor are identified as two orthogonal components that can be visualized with a vector.

What are the types of PMSM?

Depending on how magnets are attached to the rotor, PMSM motors can be classified into two types: surface PMSM (SPMSM) and interior PMSM (IPMSM). SPMSM mounts all magnet pieces on the surface, and IPMSM places magnets inside the rotor.

What are the advantages of self control of synchronous motor?

Advantage or Merits: One of the major advantage of using synchronous motor is the ability to control the power factor. An over excited synchronous motor can have leading power factor and can be operated in parallel to induction motors and other lagging power factor loads thereby improving the system power factor.

What are the advantages of PMSM motor?

Higher torque and better performance. More reliable and less noisy, than other asynchronous motors. High performance in both high and low speed of operation. Low rotor inertia makes it easy to control.

What is Pmsm stand for?

The Permanent Magnet Synchronous Motor (PMSM) is an AC synchronous motor whose field excitation is provided by permanent magnets, and has a sinusoidal back EMF waveform. The PMSM is a cross between an induction motor and brushless DC motor.

How is field oriented control used in PMSM?

This technical note presents a common control technique for Permanent Magnets Synchronous Machines (PMSM). The Field-Oriented Control (FOC) method is a motor control strategy that orients the stator current vector in a rotating reference frame of the machine.

How to tune a sensorless speed control for PMSM?

What are the parameters of permanent magnet synchronous control?

Machine parameters Parameter Value Unit Stator resistance 3.4 Ohm Stator inductance (d and q axis) 12.15 mH Permanent magnet flux 0.25 Wb Moment of inertia (PMSM only) 2.9 kg cm 2

How is field oriented control used in a synchronous machine?

The Field Oriented Control (FOC) is a form a vector control. The currents, voltages, and magnetic fluxes of the machine are expressed as space vectors inside a Rotating Reference Frame (RRF). In the case of a synchronous machine, the stator and rotor fluxes are synchronous.
