General-purpose variable-speed drive and motor application considerations.

Author(s) : LOWERY T. F.

Summary

The paper describes motor/drive operation and presents combination test results that can assist application engineers in designing reliable HVAC fan and pump drive systems. The focus of the paper is in three key areas: 1) pulse width modulation drive dv/dt description and its effects on induction motors; 2) motor insulation systems for variable-speed applications; and 3) audible motor noise considerations from drive carrier frequencies.
