Who is the Korean supplier of TECO power distribution components?

OHI Tech is the official Korean partner of TECO Electric & Machinery (TWSE 1504, est. 1956). We supply the full lineup of AC contactors (CN/CU/TMC), overload relays (RHU/EOR), and circuit breakers (TMS/MCB/MCCB/ACB), together with drone motors, UAV powertrains, and ESCs.

What is the rated range of TECO circuit breakers?

TECO breakers span from motor-protection TMS-S (0.1–32A) to miniature MCB (BM/BR 1–125A), molded-case MCCB (TCB/TAX 16–800A), and air circuit breakers ACB (TAW/BAW/TBW up to 6300A, 4000A DC switch). Certified to CSA, UL, CE, CCC, and RoHS.

What drone motor power range does TECO offer?

TECO offers light drone motors from 330W (2317 KV800) to 3802W (10010 KV110) across 10 models. For medium UAVs, the agricultural powertrain supports up to 150kg payload with 76.5kg/rotor thrust and 12.9kW peak power. Halbach Array design and Japanese bearings achieve up to 91.8% efficiency.

Which TECO motor suits large agricultural drones?

We recommend the Medium UAV Powertrain System (Drone 1), supporting up to 150kg payload with 76.5kg/rotor thrust, 12.9kW peak power, and CAN+PWM control. Five patents (in-slot air cooling, 20g shock durability, conformal coating, salt-spray resistance, anti-bearing-slip) make it proven for agricultural environments. Over 1,400 motors are produced monthly, fitted on 350+ UAVs in operation.

Can TECO contactors/breakers be used together with a VFD (inverter)?

Yes. TECO recommends the standard configuration of circuit breaker (TCB) → contactor (CU/CN) → VFD → motor. Single-brand integrated supply resolves compatibility, certification, and lead time at once. Regenerative braking and variable-speed control deliver about 30% average energy savings.

What is a TECO EC motor (ECM), and how does it differ from a conventional AC motor?

A TECO EC motor (ECM) uses BLAC PMSM (brushless AC permanent-magnet synchronous) technology, cutting power consumption by up to 70% versus a conventional PSC induction motor. Stepless speed control, Modbus/RS485 communication, and an integrated driver improve both energy efficiency and control convenience for HVAC equipment. OHI Tech supplies the full lineup: internal rotor (FCU/AHU), external rotor (FFU/cleanroom), driver boards, and integrated modules.

What HVAC applications does TECO ECM support?

TECO EC motors cover three primary HVAC applications: FCU (Fan Coil Unit) for residential and commercial buildings using internal rotor D98/D125 models; FFU (Fan Filter Unit) for semiconductor fabs and cleanrooms using external rotor OD102; and AHU (Air Handling Unit) for large commercial buildings, hospitals, and data centers. OHI Tech supplies complete system modules (motor + blower assembly) and individual EC motor components for OEM integration.
