The KM-42F540 gear motor operates at 3V with a rated torque of 30kg⋅cm, a speed of 4.5±12%rpm, and a stall current of 7.1A to meet high load requirements. Its compact size, stable output, and powerful torque control make it ideal for space-constrained systems such as coin-operated machines, smart toilet lids, and pancake machines. The motor can easily handle frequent start-stop cycles, ensuring reliable performance and long service life in daily applications.

The minimum order quantity (MOQ) of our conventional brushed DC motors and brushless DC motors is 5k-10k/Lot; and the minimum order quantity of conventional reduction motors is 1k/Lot.
Customers need to clearly provide the performance and shape requirements of the product (different shapes determine the size of the space, which will be directly related to the performance that different specifications can achieve such as torque values are different). Performance requirements include operating voltage, rated load, rated speed and other parameters, and appearance requirements include the maximum installation size, shaft size, terminal direction and so on.
In addition, if the customer has other more detailed requirements such as current limits, working environment, service life and EMC standards can also be provided together, which will help us to carry out a more accurate and comprehensive assessment to ensure that the final product can meet the customer’s individual needs.
Yes, we provide the whole brushless motor solutions including the controller.
We do not currently have any subsidiaries or agents, but we are open to future cooperation. We are always looking for partnerships with companies and individuals around the world who are willing to become our local agents, allowing us to serve our customers more closely and efficiently.
Our company has a complete range of brushless motors, and can provide motors with special structures such as coreless/outer rotor brushless motors.
