Sinotech Motors

Sinotech Motors offers high quality electric motors made in China with U.S. engineering and support. In our online motor catalog you'll find AC motor specifications, DC motor specifications, stepper motor specifications and gearmotor specifications.

We offer a wide range of DC motors including permanent magnet motors and DC servo motors See our DC Motor Selector for information on how to select the right DC motor.

For AC motors we can supply induction motors, linear motors, synchronous motors, and AC servo motors.

Today's brushless DC motors (BLDC) with their high efficiency and long life are found in automotive, medical, and industrial applications.

Advanced slotless BLDC motors have an ultra high speed output of up to 100,000 RPM. These motors are used in medical applications such as angioplasty and dentistry as well machine automation.

Stepper motors, often referred to as stepping motors, are available in steps as low as 0.36deg. and sizes from 28mm to 110mm in diameter. We also provide microstepper motors and disc motors. See our Stepper Motor Selection Matrix.

You'll find many varieties of gearmotors including AC gearmotors and DC gearmotors. We can match the motor with a wide range of gearboxes with ratios of 3:1 to 200:1 in many different power levels. See our Gearmotor Selection Matrix.

All motors and motor components are produced to the highest standards at our TS 16949 certified factories.

You can order off-the-shelf electric motors, or custom electric motors. We'll build to your design requirements. Don't have the specifications of the motor you're now using? Send us a sample motor and we'll recommend a replacement. Or use our motor consultancy services for help on applications or custom motors.

Sinotech Mechanical

Sinotech Mechanical offers high quality mechanical parts, assemblies and subassemblies. We can build individual components in process-specific factories and then assemble and test them in a factory perfectly suited to assembly and test.

Tooling for die castings can be built at low cost with high precision. You give us the die casting part drawing and we will design the tooling.

Investment castings are perfect for near net shape designs with complex geometries. Many of our investment castings are used in safety critical automotive applications.

Sand casting is an economical casting method for simpler designs produced at low cost.

Metal stampings can be produced using line dies or progressive dies. Both are economical when done in our factories. Many of our deep drawin stainless steel stampings are used in automotive applications where QS standards are required.

Formed metal tubing is another of our specialities. Many of our formed tubular products are used in fuel injection systems.

Metal extrusions of nearly any profile can be built and then CNC machined to your exacting specifications.

Injection molded components or rubber components of nearly any size and any plastic resin or rubber polymer can be built to your specification. Plastics can be thermoplastic or thermoset.

Shafts are one of the most critical components in any rotational system. We can supply shafts for complex helical drives. Or, we can build slotted and knurled shafts.

Major cost savings are available when secondary metal processing, such as machining, heat treating, and plating are done in our factories. Check out our complete list of secondary processes.
