Import Brake Three-Phase Induction Motors — Buy in Bulk from Supplier in China

Control Technology Co., Ltd. supplies brake three-phase induction motors from their facility in Qinhuangdao, Hebei Province, China. These motors integrate electromagnetic braking with standard three-phase induction operation, allowing rapid stopping and holding of load positions without external mechanical brakes. The source description indicates energy-efficient design and industrial-grade construction, though no exact kW ratings, frame sizes, or efficiency classes are listed. Buyers should request the specific IE class (IE2, IE3 or IE4) and nominal power range before selecting a model.

The braking mechanism in these motors typically uses a DC-excited electromagnetic disc brake mounted on the non-drive end of the motor shaft. Standard brake torque ratings for this product category usually range from 100% to 200% of motor rated torque, with typical brake engagement times of 0.1 to 0.5 seconds depending on frame size. Insulation systems commonly reach Class F (155°C) with Class B temperature rise reserves. The supplier notes suitability for conveyors, pumps and general machinery, which implies standard B3 or B5 mounting configurations and IP54 or IP55 enclosure protection as typical for industrial brake motors in this class.

Primary buyers include manufacturing plant engineers, mining equipment maintenance teams and logistics automation integrators who need controlled stopping on inclined conveyors or precision positioning on production lines. The supplier mentions L/C and T/T payment terms, though no minimum order quantities or confirmed lead times are stated. Given the location in Qinhuangdao near the Bohai Sea port cluster, FOB Tianjin or CFR main port terms would be logistically typical. Buyers should confirm whether the brake coil voltage matches their control system (common options: 220V DC or 380V AC rectified) and whether the motors carry CE marking under the Machinery Directive 2006/42/EC.

Control Technology Co., Ltd. operates from Park Scien-Tech Of Yanshan University, 3 20 Huanghe Ave. Etdz, Qinhuangdao 066004, in Hebei Province, China. The company's location within a science and technology park affiliated with Yanshan University suggests potential academic or research linkages, though the exact nature of these ties is not specified in the source data. The supplier is classified as an imported tier vendor with a harbor trust designation, indicating they are registered on the platform but have limited verification depth. Notably, the response rate is recorded as 0.00% with zero average response hours, which means no response data is available rather than confirming active non-response.

The listing provides no information about company history, factory size, annual production capacity, number of employees, or specific client references. No ISO 9001, ISO 14001 or other management system certifications are confirmed in the source material, despite generic claims in the original description. Buyers should independently verify factory existence through video inspection or third-party audit, request business licence copies, and confirm whether the company manufactures brake motors in-house or sources them from a subcontractor. The Qinhuangdao location offers proximity to Tianjin Port, but the supplier does not state explicit export experience or Incoterms they accept.
