QPT has actually presented MicroDyno, a low-voltage electric motor drive examination system that shows the efficiency of ultra-high regularity GaN-based electric motor drives. The system is developed to supply better control and performance while lowering system intricacy and expense, with applications in the expanding collective robotic (cobot) market.

Operating at 1 MHz changing rates, MicroDyno incorporates a portable filter to provide a real sine wave voltage to electric motors. While QPT’s IP ranges as much as high power, this low-voltage system will certainly be made use of to demonstrate how it can change the efficiency of cobots and basic robotics via the vibrant modification of torque cogging and torque surge, and high-fidelity noticing within the drive. Every one of this is accomplished without costly outside sensing units or encoders to both considerably decrease the expenses of these systems whilst likewise extremely enhancing the efficiency over conventional PWM-based systems.

Many existing robot drives run at 4– 16 kHz PWM regularities, forming existing right into a sine wave yet leaving the voltage at the electric motor as high dv/dt PWM. Some professional systems get to 100 kHz, yet these face electro-magnetic difficulties and are still as well radio frequency to allow tiny, affordable filtering system needed for real sine voltage outcome and EMI filtering system.

By drawing out the optimum efficiency from GaN transistors, it has the ability to running at around 100x the conventional regularity which allows an extremely tiny, inexpensive outcome filter, creating a tidy sine voltage straight at the electric motor terminals with an exceptionally high signal-to-noise proportion. This likewise gets rid of EMI, lowers birthing currents, allows “noticing without sensing units”, and permits the usage of unshielded wires or a completely incorporated electric motor drive– a transformative change for robotics assimilation.

Accuracy and level of smoothness: QPT’s qControl innovation can creating the 1MHz signals with picosecond precision. The little filters provide real sine voltage making it possible for cleaner control signals, supplying smoother activity vital for fragile setting up and clinical robotics.

High-fidelity sensorless diagnostics: Tidy sine wave outcome sustains sophisticated torque and resonance tracking for sophisticated noticing and anticipating upkeep. The electric motor drive can find and report on the reason for any kind of resonances in the system, all without the demand for costly outside sensing units.

Compact, light-weight assimilation: 1 MHz changing lowers filter and drive dimension, making it possible for the electric motor drives to be completely incorporated with the electric motors in the robot joints.

Reduced system and growth expenses: With the incorporated filters, costly secured cabling is not needed. EMC is likewise much less complex, electric motor life is expanded, costly encoders and sensing units can be gotten rid of, and a lot greater efficiency can be accomplished from more affordable electric motors.

AI allowed for next-generation styles: MicroDyno lays the structure for regional AI handling to enhance the efficiency of each electric motor, and a cloud-based remedy to check and maximize throughout a fleet of electrical motor systems, such as a whole assembly line of device devices or robotics.

MicroDyno shows QPT’s design at 48V for robotics and cobots, yet the underlying innovation is completely scalable. Making use of QPT’s exclusive qAttach product packaging, the very same high-frequency sine-wave benefits encompass 400V and 800V systems. The sine wave outcome likewise opens the capability for the style of multiphase components that can be made use of in alongside get to megawatt degrees of power with a much smaller sized variety of components for electric motor drive OEMs to emulate.
