DMKE motor was founded in China, Guangzhou city,Panyu district, in 2009. After 14 years' creativity and development, we became one of the leading high-tech companies in China in dc motor industry.
We specialize in high precision micro dc gear motors, brushless motors, brushless controllers, dc servo motors, dc servo controllers etc. And we produce brushless dc motor and controller with wide power range from 5 watt to 20 kilowatt; also dc servo motor power range from 50 watt to 10 kilowatt. They are widely used in automatic guided vehicle , robots, lifting equipment,cleaning machine, medical equipment, packing machinery, and many other industrial automatic equipments.
With a plant area of 4000 square meters, we have built our own supply chain with high quality control standard and passed ISO9001 certificate of quality system.
With more than 10 engineers for brushless dc motor and controllers' research and development, we own strong independent design and development capability. Custom-made motors and controllers are widely accepted by us. At the same time, we have engineers who can speak fluent English. That makes we can supply intime after-sales support and guidance smoothly for our customers.
Our motors are exported worldwide, and over 80% motors are exported to Europe, the United States, Saudi Arabia, Australia, Korea etc. We are looking forward to establishing long-term business relationship together with you for mutual business success.
