DC motors for camera, audio and data applications

In the digital age, media and processing systems are getting more advanced. This increases the need for precise, efficient and compact motor designs. EMS specialises in providing high-performance small DC motors for demanding electromechanical applications such as camera systems, audio equipment and data networks.

From powering camera cranes to ensuring accurate fibre optic splicing, our motors play a crucial role in a diverse range of drive systems. Learn about some of the camera, audio and data applications we support below.

Camera motion control

Capturing televised events such as sports and film recordings requires cameras mounted at the end of a boom to achieve highly precise shots at the perfect angle and to quickly focus in on shots.

For nature documentaries, crane setups are often used to capture clear footage. In these scenarios, it’s sometimes necessary to quickly track and refocus on the animal, and therefore to ensure the frame is secure and clear. Electric DC micromotors initiate smooth yet rapid movement in these scenarios, ensuring seamless footage through precise control and even application of dynamic power.

Drones are increasingly used for aerial footage in filmmaking, as well as for other applications such as surveying and search and rescue operations. However, stabilising the camera can be challenging. Brushless DC motors in gimbals provide precise, real-time control, keeping the camera steady even in windy conditions or during high-speed manoeuvres. Aided by this consistent motion control, drones can capture smooth, clear footage from every angle.

Record players

In high-end turntables, every detail matters for delivering exceptional audio quality. Achieving consistent playback with excellent speed control and minimal noise is essential to capturing the warmth and clarity of vinyl records.

FAULHABER motors make this possible. With smooth, stable operation, these motors ensure that the turntable platter rotates at an exact speed, preventing variations that could distort playback. Additionally, low running noise eliminates interference, preserving the purity of the sound.

By minimising vibrations and regulating speed with pinpoint accuracy, DC motors help to deliver an authentic and immersive listening experience. From the subtle tones of acoustic guitar to the powerful dynamics of a symphony, every note plays as it was meant to be heard.

Fibre optic splicing

Fibre optic splicing is vital for high-speed communication. It involves carefully joining two optical fibres to create a continuous path for light signals, ensuring that data can travel efficiently over long distances without interruption or loss. This process is crucial for everything from internet connection in homes to medical imaging systems in hospitals, where flawless data transmission is a must.

The accuracy of each splice directly affects the performance and reliability of the entire network, so precision is key. Even the smallest misalignment could result in signal loss, latency or network failure.

DC motors play a critical role in fibre optic splicing by providing the precise movement needed for accurate fibre alignment and splicing. Whether driving the fine-tuned motion for aligning the fibres, powering the cutting tools for clean, sharp fibre cleaving or ensuring stable operation throughout, DC motors deliver the smooth, reliable performance necessary for such an intricate process.

Case studies

Leading the Light Revolution

Czech photographer Miroslav Tichy once said that photography is simply painting with light. With the support of EMS, Light Revolution, a lighting and camera system manufacturer for the film, photography and photogrammetry industry, has taken the concept of painting with light straight into the 21st century.
