Import 50 Kg Load Torque Brushless 50w 12v Dc Motor — Buy in wholesale FOB from Supplier in China

The JGB37-550 model from Qiandi(Guangzhou) Electronic Tech Co., Ltd. is a brushed DC motor, not brushless as the product title suggests, rated at 50W and 12V with a claimed load torque capacity of 50 kg. This is a made-to-order product with a listed MOQ of 350 units and a production cycle of 7 to 15 working days after order confirmation. The supplier emphasizes that all specifications require pre-order confirmation, and the product is not held in stock.

The JGB37-550 designation indicates a 37 mm diameter gearbox with a 550-type motor, a common form factor in small DC gear motors where the number denotes the motor can dimensions rather than output power. A 50 kg load torque rating at the output shaft typically implies a substantial reduction ratio, likely 100:1 to 300:1 depending on output speed requirements, though the exact ratio and corresponding rated speed are not stated. Brushed motors in this class use carbon brush commutation with expected service life tied to brush wear, typically 500-2000 hours depending on load and operating conditions. The 12V supply voltage is standard for battery-powered and low-voltage control systems, with 50W representing the electrical input power, not mechanical output.

Applications cited by the supplier span smart car drives, automated doors and windows, vending machine dispensers, smart home actuatorsPulse-width modulation (PWM) speed control compatibility and direction reversal capability are standard for brushed DC motors and should be confirmed with the supplier. Buyers should request the full performance curve showing torque, speed, current, and efficiency across the operating range, as well as noise level in decibels for noise-sensitive installations. The Guangzhou location offers access to Shenzhen and Hong Kong logistics corridors for international shipment.

Qiandi(Guangzhou) Electronic Tech Co., Ltd. is located at No. 37 Dongpeng Avenue, East District, Huangpu District Development Zone, Guangzhou City, Guangdong Province, China, postal code 510760. The company operates from a specific industrial address in the Huangpu Development Zone, a manufacturing and logistics hub in Guangzhou's eastern district. The supplier is listed with a harbor trust tier and has a 0.00% response rate with zero average response hours recorded, indicating no engagement metrics are available.

The business model combines wholesale, retail, and on-demand custom processing for DC motors in the 3-24V range. The supplier offers both brushed and brushless variants, though this specific listing is for a brushed motor despite its title. The contact person is identified as Mr. Paul Lee. No information is provided about factory floor space, employee count, annual turnover, quality certifications, or export license status, and these should not be invented. Customization capability is stated, but the extent of engineering support, prototyping services, and IP protection protocols must be confirmed directly.
