What SCHLEICH Advanced Test Technologies does

SCHLEICH Advanced Test Technologies (legal entity: SCHLEICH GmbH) is a privately held German industrial testing equipment manufacturer founded in 1952 and headquartered in Hemer, Germany. The company specializes in electrical safety testing and motor/winding testing technology, producing both standardized and modular test systems used by manufacturers of electric motors, generators, transformers, and finished electrical products. Its core product families include the GLP series (GLP1, GLP2-BASIC, GLP2-MODULAR, GLP2-R, GLP2-BT, GLP3) for general safety and function testing, the MotorAnalyzer series for portable motor diagnostics, and the MTC series (MTC2 R7, MTC3 R2) for surge voltage and partial discharge testing of windings. The SCHLEICH-MODULAR-CONCEPT allows customers to combine multiple test methods into a single configurable device, while a broad accessories portfolio (matrix modules, test plugs, probes, calibration resistors, safety hoods and booths) supports integration into complete EOL test stations and manufacturing lines.

The company generates revenue primarily through capital equipment sales, complemented by calibration services, technical support, and spare parts. Pricing is not publicly disclosed and follows an enterprise direct-sales motion with technical consultation and live demonstrations. SCHLEICH serves seven primary verticals: electric mobility and automotive, renewable energy, lighting, medical technology, household appliances, rail and aerospace, and motor repair/maintenance. Named enterprise customers include Audi, BMW, Mercedes-Benz, Volkswagen, Continental, Bosch, Siemens, ABB, Philips, Philips Medical, Miele, Electrolux, Osram, Trilux, Bombardier, Deutsche Bahn, Airbus, Vestas, Siemens Wind Power, and Thyssen-Krupp. International sales are executed through regional channel partners (MDS in North America, VOLTA in Italy, ASTAT in Poland) and an active trade show calendar (Coiltech, EASA Convention).

Emerging players

• ALL-TEST Pro: Specialist in motor circuit analysis, de-energized motor testing, and condition monitoring for motor repair shops; competes with SCHLEICH's MotorAnalyzer in the motor service and predictive maintenance market.
• FRANK- PTI (Friedrich): German testing equipment maker for stator and rotor windings of electric motors and transformers. Directly comparable niche manufacturer in the same motor/winding testing field as SCHLEICH.
• KWS Electronic Prüftechnik: German specialist in winding test systems and electronic test equipment for motor and coil manufacturers; competes head-to-head with the MTC and Wickelautomaten product lines from SCHLEICH.
• HV Technologies (High Voltage): Manufacturer of high-voltage test equipment including surge testers and PD instruments for motor and coil winding applications; product overlap with the Stoßspannung and Teilentladung lines of SCHLEICH.

Direct peers

• Hioki E.E. Corporation: Japanese manufacturer of electrical test and measurement instruments including insulation testers, resistance meters, and motor/winding analyzers directly overlapping with the GLP and MotorAnalyzer product families. Both target automotive and industrial motor manufacturers.
• Megger: Global manufacturer of electrical test and measurement equipment, including the Baker Instruments line that is a direct competitor to SCHLEICH's surge voltage and partial discharge motor/winding testers. Both serve electric motor and transformer manufacturing QA needs.
• OMICRON electronics: Austrian-headquartered specialist in electrical testing for power equipment including transformers and rotating machines. Competes with SCHLEICH in high-voltage and partial discharge testing for wind turbine generators, traction motors, and large industrial motors.

Broad incumbents

• Keysight Technologies: Large public test and measurement company whose oscilloscopes, source measurement units, and power analyzers compete in adjacent slots within EV-motor development labs and manufacturing test benches that SCHLEICH also serves.
• AMETEK (Power & Industrial Test Solutions / Baker Instrument): Large public industrial conglomerate whose Baker Instruments division makes surge testers and motor analyzers competing with MTC3/MotorAnalyzer lines. AMETEK also offers broad electronic instruments and leverages scale advantages in sales coverage and service.
• Fluke (Fortive): Global leader in portable electrical test instruments including insulation testers, multimeters, and motor/drive analyzers. Overlaps with SCHLEICH on safety and insulation testing but does not specialize in surge/PD winding testing at the depth of MTC3 R2.
