Advanced Controllers for High Frequency, BLDC and Asynchronous Spindle Motors

Motor Controllers for High Frequency Motors & Spindles

High-speed motor technology has rapidly evolved, making motor speeds of over 100,000 RPM increasingly common. While this advancement offers significant performance benefits, many traditional motor control methods have struggled to keep up.

At Zikodrive, our research and development is focused on addressing this challenge with motor controllers for high-frequency motors and spindles that are both cost-effective, efficient and easy to use. As with all walks of life, things become more complex and harder to manage as they speed up. That's why we've invested considerable R&D resources into developing robust, high frequency solutions that are IEC 61800 compliant.

Whether you're working with brushless DC or asynchronous motors, we have completed a range of projects in this area. If you need specific advice or support for a high-speed motor project, our team is ready to help.

Addressing the Challenge of Low Inductance

The biggest challenge in high-speed and high-power density motor operation is managing low inductance. Many traditional sensorless motor drive methods fail to operate with such low inductance, which often forces engineers to compromise motor performance or introduce complex sensors.

We have invested heavily in developing a motor drive method that can successfully operate in motors with low inductance. This technology is designed to help you get the maximum performance possible from your motor in the most efficient way possible.

Solutions for Sensorless Control

Sensorless control can offer cost savings without sacrificing performance. Increasingly, brushless motors are proving to be a popular choice due to their extended life and unique properties, and many of our customers are looking for a low-cost, sensorless brushless option.

Zikodrive has a strong focus on high-speed sensorless motor control, ensuring our solutions are reliable and effective. Our advanced motor controllers and back-EMF monitoring technology enable superior, consistent performance.

FAQs

Can Zikodrive design custom controllers for both BLDC and asynchronous motors?

Yes, absolutely we can. Indeed, depending on your specification requirements, it is quite feasible that the same controller could be used to drive both BLDC and asynchronous motors interchangeably. Why not have a look at our custom motor control design page to find out more about how we could help?

Is there a difference between a 'standard' BLDC controller and one specified for high frequency?

This is a difficult question and, as with many engineering and scientific questions, the answer is it depends.

For example, there are cases where exactly the same motor control technology can be used at low speeds and higher speeds. However, at really high speeds, the ability of methods such as FOC to be able to operate effectively can start to deteriorate, especially where low inductance (and therefore high frequency) is an issue. There are therefore a number of methods that can be employed to drive such high frequency motors more effectively.

To what extent does efficiency reduce when operating at very high speeds?

Not necessarily at all. As with the question above, there are cases where it can reduce, but this does not necessarily need to be the case. One unintended side effect of improving high speed performance can be that the lower speed performance suffers from power efficiency. However, Zikodrive Motor Controllers can design motor controllers that transition between operating states to give the best of both worlds.

What do we mean by 'high frequency' motors or spindles?

The concept of high frequency can mean multiple things in motor control so it is important to be completely clear on this question. In this instance we are referring to what most people would call high speed motors. In other words, motors that are typically operating at 10KRPM or more.

What quality management and compliance options do you offer?

We have successfully completed projects for high frequency motor controllers that operate up to 100000RPM and are IEC 61800 compliant. Managing the risks associated with such projects is not easy and requires specialist knowledge and skills. However, our team have a proven record of delivering in this area and can support your motor control design project needs including support for EMC testing and other compliance requirements.

We operate an ISO-9001 certified quality management system for design and manufacture of motor control electronics to a range of standards as required. If you don't see the standard you're looking for, please do contact our team as we may well be able to help.
