Schleich GmbH has built motor and transformer test instruments from Hemer, Germany since 1959. Surge testing as a quality discipline, partial discharge detection as an OEM standard, the waveform conventions now cited in IEC and IEEE specifications: those methods originated in Schleich's labs.
Motor Diagnostic Systems was founded in 1997 to bring those methods to the North American electric-motor industry. Over multiple decades, the relationship narrowed and deepened. Other distributors came and went. MDS remained, gradually consolidating territory, service authority, and calibration credentials until the appointment became formal: exclusive North American distribution, sole authorized service.
Today the partnership covers every Schleich product line deployed on the continent. Every after-sale event. Every calibration certificate. Every parts order. One contract. One accountable party. No parallel channels, no grey-market routing, no ambiguity about who answers the phone when a tester is down.
