Breaking the ice:
Introduce your request, and any other information you’d like to know about this Solution.

Add a message before sending your request.

We support the entire product life-cycle, from the design and selection of gearmotors to high volume supply with on-going quality control and testing.

About this Solution:

With a wealth of experience we will help you realise your product, and support you through the entire process from prototyping up to production. Our engineering staff are from a variety of professions, and we take a holistic approach from the get go.

Who are we?

We’re a cohesive team with a passion for helping develop new products. The majority of staff have an engineering or technical background, and we relish any opportunity to get involved and solve a new or interesting challenge. On a daily basis our offices are hives of hacking, making, tinkering and building.

Where are gear motors used?

Our gear motors have been used in various applications such as:

  • Smart locks
  • Medical equipment
  • Laboratory equipment
  • Consumer electronics

How to choose a gear motor?

Rather than diving straight into specifications and datasheets let’s discuss your application, and what you’re working towards. Once we’ve got an understanding of what you’re trying to achieve we can look to identify possible pitfalls and challenges that lay ahead.

While we may deal with gear motors every day we appreciate that you may not be so familiar with them, and it is likely just one piece of a much larger puzzle.

Why are PMD gear motors a great choice?

Besides the consistently high quality you’ll find that our gear motors are cost-effective and reliable.

Choose Geared Motor

Great, do you have any examples?

We consider the privacy of our customers to be very important, regardless of whether we have a mutual NDA in place. While this limits the detail we can go into, we can tell you that we’ve worked with:

  • a number of the major smart lock companies
  • laboratory equipment companies
  • various companies developing products for the administration of pharmaceuticals

What are common specifications of these gear motors?

With a broad range our gear motors can have various characteristics.

  • 1.5 to 24VDC
  • As small as 6mm in diameter!
  • Up to 7 Nm of torque
  • Up to 1,800 RPM

Our application is revolutionary/demanding/radical, can you customise a gear motor?

Of course! Some customisations, like rewinding for a different drive voltage, are very cost effective so don’t hesitate to ask. The possibilities are (nearly) endless, but some of the more common customisations include

  • Specific driving voltages
  • Modified performance (namely output speed and torque)
  • Custom length wire sets with connectors
  • PCB backpacks for speed or positioning control

We’re only in the early stages, can you support smaller quantities?

We understand that when developing a product the initial quantities can be low, so we work to accommodate smaller order quantities where possible. To make designing easier we also provide CAD models and comprehensive datasheets.

What are the first steps?

Firstly, get in touch. Even a journey of a thousand li starts with a single email.

Then, once we have an understanding of your application, we can determine the preliminary requirements relating to:

  • Size and form factor
  • Output torque and speed
  • Driving voltage

From there we can go through the sampling and prototyping stages

Where are we?

We have offices and test facilities in Shenzhen, Hong Kong and London. Our global workforce can provide support in:

  • English
  • Mandarin
  • Cantonese
  • Spanish
  • French
  • Flemish/Dutch
  • Afrikaans


Certifications Acquired:

  • ISO9001

Potential Applications:

Our gear motors have been used in various applications such as:

  • Smart locks
  • Medical equipment
  • Laboratory equipment
  • Consumer electronics
