Sinbad offers four motor series to help you meet a wide range of requirements, whether they are DC brushless motors, very high torques or very high speeds. The patented U-coil offers outstanding performance, including minimal iron loss, higher efficiency and lower operating temperature.


A design is definitely not all. Not when your application has specific performance requirements for high speed, high torque, or a delicate balance of the two. Not when you need to deliver superior performance at the best cost. Our 4070 DC motor fits this very well. Electric brushless DC motors are manufactured using our patented copper coil winding technology. This new coil design, designed in the tech world, is key to the performance of these brushless micromotors, including minimum core loss, higher efficiency and lower operating temperature.


Looking for super speed and maximum response speed? The 4070 DC motor is designed for high speed, direct drive applications.
