Electric motors
are ubiquitous in modern life, from climate control, appliances and commercial refrigeration to cars, factories and infrastructure.
According to the International Energy Agency, electric motors account for 45% of total global electricity consumption, so the reliability and energy efficiency of motor-driven electronics have an impact on comfort, convenience and the environment in a variety of applications around the world.
One way to improve the energy efficiency of motor drive systems is to replace single-speed motors driven at 50/60 Hz AC line voltage with variable speed drives, which enable electronic speed control of the motor and higher drive efficiency. Variable speed control can also provide high energy efficiency at the application level compared to on/off regulation methods.
The heart of an advanced motor drive system is the inverter stage, which receives the incoming DC power and converts it into an AC voltage with the frequency to drive the motor at the required speed. The inverter consists of three half-bridges, as shown in Figure 2.
Each half-bridge phase of the inverter has a high-side and low-side switch, which can be silicon power MOSFETs, IGBTs, silicon carbide (SiC) FETs or gallium nitride (GaN) high electron mobility transistors (HEMTs), depending on the application requirements.
For example, the requirements for turning a pump or fan, a conveyor motor or a robotic arm are different, and industrial applications will utilize different motor technologies to suit each situation: AC motors, brushed or brushless DC, permanent magnet synchronous motors (PMSM) or switched reluctance for example.
Regardless of the wide range of applications and technologies, if we look at the factory environment, drive systems always need to meet the following basic common requirements:
High energy efficiency and reliability
Safety, reliability and integration
Durable and excellent thermal performance
Developing efficient and reliable motor drives that meet all of these requirements is complex and time consuming, but with ON Semiconductor's new Motor Development Kit (MDK) , it's easy.
This comprehensive prototyping platform includes the Universal Controller Board (UCB) which connects to an extended power board option to create a quick start platform to run your motor, allowing rapid testing, evaluation and optimization of the system before designing any hardware.

UCB uses the powerful Xilinx Zynq®-7000 Field Programmable Gate Array (FPGA) / ARM System-on-Chip (SoC) for high-end control and artificial intelligence (AI)-based applications. UCB is fully compatible with Xilinx development tools and libraries and was developed in collaboration with Trenz Electronic.
These power boards contain ON Semiconductor's leading power devices and modules, as well as all other necessary components from our extensive product portfolio to develop a complete motor drive solution.
The first two power boards feature our Intelligent Power Modules (IPMs) for industrial and appliance motor drive applications. The IPMs integrate six power switches for the inverter, gate drivers, and a thermocouple, and their protection features include overvoltage/undervoltage lockout, shoot-through protection, and overcurrent trip.
The compact IPM power board (SECO-1KW-MCTRL-GEVK) provides a complete solution from AC input from the mains to AC output for the motor.
Rated for 230 Vac input voltage, it includes an EMC filter and bridge rectifier, interleaved two-channel power factor correction (PFC) and NFAQ1060L36T IPM as the inverter stage, as well as auxiliary power supplies, measurement and protection.

For higher power levels, the SECO-4KW-65SPM31-GEVB power board uses the NFAM5065L4B 650 V smart power module.
It is rated for 400 VDC input voltage and can deliver up to 1 kW of continuous power, and can deliver up to 4 kW for short periods of time or with the addition of a heat sink. This product is ideal for industrial drives and commercial HVACR applications.

Coming soon will be a series of power boards featuring our best-in-class MOSFET lineup . These motor driver boards will support input voltages from 10 V to 100 V with power capabilities up to 1.2 kW to address battery-powered and low- to medium-voltage applications such as power tools, robotics, autonomous robots, and drones.

We have also developed more power boards, highlighting our extensive IPM lineup with new modules for higher power motor drive applications. The modular design also allows us to adopt a range of PFC schemes, allowing the freedom to mix and match power conversion stages to optimize to your requirements.
ON Semiconductor’s new Motor Development Kit (MDK) includes a Universal Controller Board (UCB) for a common control platform and an expanding range of power boards to quickly test and evaluate comprehensive motor drive solutions.
A 1 kW 600 V board based on the compact IPM and a 4 kW 650 V board based on the SPM31 will both be available in the fourth quarter of 2020.
There will also be a power board based on ON Semiconductor’s TMPIM technology to drive motors up to 10 kW to be released in the first quarter of 2021. ON Semiconductor will add more power boards and expanded design support to the MDK ecosystem.
