siliXcon Double Motor Controller

A Solution for Specific Applications

When designing electric drives, it is crucial to choose a solution that meets the needs of a specific application. One option that proves to be effective in certain situations is the double motor controller – a dual controller capable of efficiently operating motors with two windings. 🔧

How Does a Double Motor Controller Work?

A double brushless motor controller is most commonly used in systems where it is necessary to control two separate motors or a motor with two independent windings. This principle is often utilized in axial motors, such as the PMS series from Heinzmann. These motors feature a sandwich structure – two windings on the sides and a rotor in the middle. ⚙️

Using a double controller allows for doubling the output current, leading to an increase in torque and motor power. This solution is particularly attractive for applications where increasing voltage is not possible or desirable. 🚀

Advantages of a Double Motor Controller ✅

• Increased Power – By controlling two windings in parallel, it is possible to efficiently scale the output power and torque. ⚡️
• Utilization of Existing Batteries – Allows the system to remain at low voltage while using the existing battery in the vehicle. 🔋
• Higher Safety – Lower voltage reduces risks when working with electrical systems. 🛡️
• Flexibility for Specific Applications – Enables performance optimization for particular motor types and drive systems. 🔄

Disadvantages of a Double Motor Controller ⚠️

• Higher Losses at High Current – Electrical power is defined by the formula: voltage × current. If voltage cannot be increased, the current must be increased, leading to higher ohmic losses. ⚡️📉
• Thicker Wires Required – At higher currents, conductors with a larger cross-section are necessary, which can be a structural challenge. 🏗️
• Limitations in BMS – The market lacks many high-performance BMS solutions capable of handling such high currents at low voltage. 🔌
• Need for Special Components – Additional elements such as contactors may be required for proper functionality. 🛠️
• Requirement for Synchronized Rotor Position Signal – Ensuring synchronization between controllers is essential for proper motor operation. 🎯

Is a Double Controller the Right Choice for You? 🤔

A double Brushless Motor Controller is not a universal solution, but it can be highly effective in specific cases. If you need to increase power while maintaining low voltage and safety, it could be the right choice for your system. However, it is essential to consider the potential drawbacks and technical requirements. 💡
