Low-Voltage AC Motors for Equipment Electrification
Electrification with AC Motors for Mobile Systems
Performance, efficiency, and reliability are all necessary considerations in electrification projects for mobile work machinery. This is especially true when transitioning from internal combustion engines (ICE) or traditional DC brushed motor systems.
At Cross Company’s Mobile Systems Integration Group, we specialize in delivering expertly tailored AC motor solutions designed to meet the unique demands of your particular application.
Why Use AC Motors?
AC motors have become the go-to choice for equipment electrification projects due to their high efficiency, longevity, low maintenance requirements, and wide speed and torque ranges.
Because of limited space on mobile equipment, and the cost of batteries, you want and need the most efficient motors when electrifying your equipment. That, along with their longevity and low maintenance requirements, in most cases, make them the right choice for your machine.
Low Maintenance
Unlike DC motors, AC motors are brushless, eliminating wear and tear components. There is little to no maintenance required for these motors. Less service means less cost for both you and your customers.
Increased Longevity
Within the application itself, AC motors are simpler in operation and are able to last significantly longer under strain due to a decrease in moving parts such as brushes seen on DC motors. Additionally, the paired inverter will monitor the temperature sensor embedded in the motor and reduce power delivery if the motor reaches a high temperature set point, preventing any thermal damage.
Higher Efficiency
AC motors are typically able to achieve 95% efficiency compared to roughly 80-85% for DC motors. This translates into extended battery life, less heat generation and reduced cooling needs, and increased duty cycle for mobile systems.
Wide Speed and Torque Range
Both asynchronous (induction) and synchronous (brushless permanent magnet or synchronous reluctance) AC motors offer high flexibility across a broad range of speeds and torque requirements. By being able to control these motors precisely by either using speed or torque commands, you gain the ability to have very precise control over your machine function.

Synchronous vs. Asynchronous AC Motors
When comparing synchronous versus asynchronous AC motors, there are several considerations to be made based on your specific application. Factors like space claim, vehicle size, job function, cooling needs, travel distance, cost, as well as others, can help determine the right motor for your machine. Cross Company and our MSI group can help you select the right motor for your needs.
Synchronous Motors – Extremely efficient, making them ideal for electrified, battery-powered systems. This efficiency reduces wasted energy, extends battery life, and minimizes heat production within the system itself.
Asynchronous Motors – Cost-effective and easy to manufacture, making them an ideal choice for budget-sensitive projects
