Standard features of all EMAs
Sampling rate and accuracy
Digital position sensor that samples data at a frequency of 20 kHz with an accuracy of 50 nm. To ensure there is no phase shift in the data, we simultaneously read force measurements at the same 20 kHz speed using an analog sensor.
Supported waveforms
EMAs support all standard waveforms—Sine, Triangle, Square, Pulse, or Custom. Import and replicate telemetry data from MoTeC and BYB.
Inputs for analog sensors
All EMAs come with three more inputs capable of sequentially reading other analog sensors at 20 kHz for comprehensive testing. Additional channels allow to monitor pressure, temperature, acceleration, noise, and other important factors at the same time.
Noise levels
On standby, EMA produces around 55 dB of background noise. When electromagnetic actuators are activated the noise levels depend on the velocity of the test. They range from as low as 60 dB. This makes EMA an ideal solution to test suspension components for any EV.
Power input requirements
EMA does not require an extensive power infrastructure. It uses an innovative power supply system that relies on supercapacitor packs. Because of this, it can run on a standard three-phase 8A power input.
Custom applications
In-house developed components allow us to have full control of compatibility and upgradability. Not to mention it opens opportunities to innovate and create 100% custom features.
What makes EMA special?
Components developed in-house
Data logger
The data logger for EMA is a marvel. Our engineers developed it in-house with the sole objective of detecting even the tiniest force changes in damper performance.
It delivers an impressive position resolution of 50 nanometers and a sampling rate of 20 kHz. The load cell resolution and sampling rate are equally impressive of 20-bit and 20 kHz.
Our data logger supports multiple analog output and input channels to maximize versatility of the machine.
Control unit
The control unit of EMA is integrated with a data logger into a single board. This solution allows us to provide the most accurate test results in real time.
Incorporating state-of-the-art technologies such as silicon carbide (SiC) MOSFETs allowed us to generate significantly more power at a fraction of the cost.
Additionally, this unit controls the operation of the smart power supply, enhancing the efficiency of EMA by LABA7 while reducing energy consumption.
Power unit
The smart power supply unit of the EMA is the first and so far only such solution in the market. The high-voltage power supply to the actuators, facilitated by supercapacitor packs, eliminates the dependency on high voltage/amperage input.
While the larger EMA versions require a three-phase 380 V 8A power input, the smallest model can operate from a standard one-phase 220/240 V outlet.
This innovation opens up new possibilities, allowing any suspension workshop to own and utilize an electrodynamic linear actuator for the first time.
Software
LABA7’s software for electromagnetic damper test systems is designed with user experience in mind. Operators can easily find, manage, and customize the features of the tests minimizing the onboarding time.
Our software for EMA allows pre- and post-test editing of data. To save time, it enables operators to trim track data and test damper performance in specific stages of the course. After the test operators can slide and cut graphs as well as push individual cycles on top of each other for better data analysis.
The software enables seamless integration with additional sensors and testing equipment.
It also includes LABA7’s shock dyno library, a cloud-based service that allows users to easily record, store, and share test data across departments. This feature supports tests conducted with both electromagnetic actuators (EMAs) and Scotch-Yoke shock dynos.

Electromagnetic vs Hydraulic damper testing systems
Electromagnetic and hydraulic damper test systems are two distinct technologies used to evaluate and test dampers in various applications.
Electromagnetic actuators provide high precision in force control with quick response times. They excel in handling a wide range of frequencies and operate quietly, thanks to fewer moving parts and the absence of fluid dynamics. Additionally, these systems require less maintenance and experience minimal downtime, making them highly efficient.
On the other hand, hydraulic damper testing systems are designed to generate the higher forces needed for testing large or industrial dampers. Especially in lower-frequency testing. However, hydraulic systems demand regular maintenance due to potential leaks, fluid replacement needs, and the wear and tear of mechanical components. Moreover, they have more stringent health and safety requirements for operators compared to electromagnetic test systems.
Unleash the power of your suspension
Performance comparison
Whether evaluating left versus right dampers, front versus back setups, or simply assessing different damper settings, our software offers seamless before-and-after visualizations. This feature is indispensable for showcasing improvements to clients during servicing or tuning sessions.
Diagnostics
Diagnose damper issues swiftly and accurately. LABA7 shock dyno software generates multiple graphs in real time, providing immediate insights into shock or fork behavior during compression and rebound. Whether it’s identifying blocked oil passages, broken shims, or cavitation due to insufficient gas pressure, our dyno graph swiftly pinpoints the root cause of any anomaly.
Ultra-fine tuning and adjustment
Navigate tuning and adjustment processes with ease. EMA replicates a wide range of waves and impulses bringing shock absorber testing as much to real-life conditions as it is possible. In addition to that the data is of extremely high accuracy, allowing you to make informed adjustments tailoring damper to individual preferences. By interpreting graphs alongside, you can ultra-fine-tune the suspension to meet even the most demanding requirements that translate into tangible on-track improvements.
Quality control and warranty
Ensure quality and uphold warranty standards through rigorous quality control measures. Before customer delivery, subject dampers to dyno testing to swiftly identify and rectify potential errors. This proactive approach guarantees customer satisfaction and minimizes the risk of warranty claims.
