Matched to your operating point
As load rises, a DC motor slows down and draws more current. Efficiency peaks at one point on the curve.
Every model page lists the speed, current and torque at maximum efficiency. You can see where your load sits before you ask for samples. If no catalogue model fits, we change the winding or gearbox to move the curve.
Three ways to work with us
Most customers start from a catalogue motor and change what their product needs.
Catalogue motor
Choose a model from our range and order samples as listed.
- Full data and drawings online
- Samples of the listed versions
- Fastest route to a quote
Modified motor
Keep the frame and change the parts your product needs.
- Winding for your voltage and speed
- Gearbox length and ratio
- Shaft, leads and connector
Custom design
A motor built to your drawing, from first sample to volume production.
- Our engineering department proposes the design
- Samples made in our sample workshop
- Production to the approved specification
Our factory in Changzhou
Engineering, sample making, quality control and assembly sit under one roof in the Wujin Economic Development Zone, so the people who design your motor are a few metres from the line that builds it.
- In-house
- Engineering and sample workshop
- Automated
- Assembly lines for volume orders
- 3 checkpoints
- Incoming, in-process and final inspection
- Shanghai
- Nearest export port
