Technical FAQs 4

What is a permanent magnet synchronous motor (PMSM)?

Permanent magnet synchronous motor (PMSM) and permanent magnet brushless DC motor (PMBLDCM) drives find wide application as industrial drives and in electric vehicles. These motors are inverter driven and require sensing of rotor position information to generate gate pulse for the inverter to rotate the rotor in the forward direction.

What are permanent magnet brushless DC motors used for?

Permanent magnet brushless DC motors are used in laser printers, hard disc drives and electric vehicles [2, 27]. Electronic switching of the six-step inverter is controlled by the rotor position which is sensed by using either the optical or the Hall effect sensors [2, 3, 4, 5].

What is IPM - interior permanent magnet?

With the technology of integrated permanent magnets (IPM - Interior Permanent Magnet) in the IE5 solutions with synchronous motors of the DR2C.. series, we have equipped the module of our motors in the portfolio with more efficiency and made it future-proof: an extension of the existing motor modular system designed for inverter operation.

How do inverter motors work?

These motors are inverter driven and require sensing of rotor position information to generate gate pulse for the inverter to rotate the rotor in the forward direction. The sensing of rotor position can be using sensors which work on Hall effect, phototransistors and disc encoders.
