Smaller, faster, and Matter-compatible, this sleek new lock is a worthy August replacement — with a few quirks.

Consumer Reports runs a battery of tests, including using a 100-pound battering ram, to help identify the best and worst door locks.

This article presents an analytical derivation of transient performance deterioration for high-speed surface-mounted permanent magnet synchronous machine (SPMSM) drives under parameter mismatches, ...
