Canadian Standard CSA C392 2nd Edition Published

Canadian Standards Association logoThe formal designation and full title for this standard that was published in April 2020 is, “CSA C392:20 Testing of Three-Phase Squirrel Cage Motors During Refurbishment.” This is the second edition of the standard and supersedes the previous edition published in 2011. The standard focuses on the identification of those tests that help to determine whether the efficiency of a motor is maintained after it is “refurbished,” without requiring a motor efficiency test.

The detailed descriptions of the tests to be performed make this standard very useful as a reference and a how-to document for any service center, not just those in Canada.

Eddy-Current Clutches and Fluid Couplings

November 2020 Webinar

Because eddy-current couplings and fluid couplings are uncommon, the institutional knowledge about them is being lost. This webinar recording is intended to preserve the knowledge of how they work as well as their unique repair requirements.

Tech Tip: Using Variable Frequency Drives (VFDs) with Emerging Technology Motors

Although some newer (emerging) technology motors can be operated with conventional VFDs, others cannot. See the table below for the use of VFDs with the various technologies.

Motor Type VFD Requirement
Permanent Magnet
• Hybrid permanent magnet (HPM) motors Special VFD needed
• Across-the-line start PM (LSPM) motors VFD not needed
High Torque, Low Speed Permanent Magnet Motors
• Surface permanent magnet (SPM) motors Special VFD needed
• Interior permanent magnet (IPM) motors Conventional VFD can be used
Reluctance Motors
• Synchronous reluctance motors (SynRM) Conventional VFD can be used
• Switched reluctance motor (SRM) Special VFD needed
Written Pole Motors VFD not needed
Printed Circuit Board (PCB) Motors Special built-in drive needed

Safety Tip:Material Handling & Lifting

Using cranes safely

  • Use a hoist or crane where loads are too heavy to handle by hand.
  • In carrying loads with other workers, always give adequate warning of any action you are about to take, such as dropping your end of the load. Keep in step; it makes the load easier to handle.
  • All truck drivers must be out of the cab and in the clear while trucks are being loaded or unloaded, unless the cab is equipped with a protective roof.
