50kg-A5840-31zy 6-24V DC Motor supply

The A5840-31ZY from Qiandi(Guangzhou) Electronic Tech Co., Ltd. is a brushed DC gear motor rated for 6-24V DC input and 5.5-24W output power, designed for applications requiring controlled torque at moderate speed. The unit measures 154.5 mm in length, 40 mm in width, and 34 mm in height, with a net weight of 480g per motor. This is a non-stocked, build-to-order product with a manufacturer-stated MOQ of 560 units and a production cycle of 15-25 days after order confirmation.

The motor employs a brushed commutation structure, which trades some service life and electrical noise for lower unit cost and simpler drive electronics compared to brushless alternatives. Gear reduction is integrated into the housing, allowing the motor to deliver higher torque at reduced output speed (exact ratio and no-load speed are not specified in the source and must be confirmed with the supplier). The 6-24V voltage range provides flexibility for battery-powered and fixed-voltage industrial applications alike. Typical brushed DC gear motors in this power class use carbon brush assemblies with copper commutators and sintered bronze or steel gears, though the exact materials for this model require verification.

Buyers for this motor span automotive prototyping, smart home actuator manufacturers, medical device makers, and industrial automation integrators, with the supplier citing specific uses in automatic doors, vending machines, medical instruments, and parking lock mechanisms. Because this is a custom-order item with no stock on hand, prospective buyers must obtain written confirmation of specifications, pricing, and delivery before committing. The supplier notes that other DC motor configurations can be customised, suggesting engineering flexibility for volume orders.

Qiandi(Guangzhou) Electronic Tech Co., Ltd. maintains its registered address at No. 37 Dongpeng Avenue, East District, Huangpu District Development Zone, Guangzhou City, Guangdong Province, 510760, China.
