Magnetek’s M-FORCE® SD500 Severe Duty AC Combo Drive System is part of our proven line of state-of-the-art industrial controllers. The system can be connected to induction AC motors for high system efficiency at a wide range of motor speeds. The DC input, AC output drive can be used in a variety of applications including battery-operated mobile vehicles. This compact package combines two variable frequency drives of two different commonly used horsepower ranges.

Features & Benefits

Features and Benefits


The rugged controller monitors and controls the system’s M-FORCE® SD Drives providing operation and fault reporting. The Controller provides full-time monitoring of motor drive temperature, battery health status, system faults, run time, and a host of other features.


  • CAN-Bus Communication
  • Wireless RF capability
  • Analog/digital inputs from gas pedal, joystick, temperature transducers and other switching devices
  • Inputs from PLC and other controllers
  • Multi-language display


The display in a MSHA approved housing provides real-time performance monitoring of the control system through the controller. External controls allow for system programming and re-configuration, data reporting, and troubleshooting within a permissible area.


The M-FORCE® Accelerator Foot Switch provides “on/off” and “speed” reference signals to solid-state controllers such as traction or variable frequency drives. This rugged, all metal device is ideal for harsh environments and off-road electric vehicles in material handling and mining. The gain and offset settings can be factory configured for specific applications, eliminating the risk of improper field adjustments, and resulting in increased safety and reliability. The device offers a magnetic rotary sensor instead of a resistive potentiometer device but still uses an electro-mechanical neutral sensing snap switch for added safety and provides trouble free operational cycles.


Magnetek can provide custom-designed engineered power solutions for applications such as transportation, mining, marine or locomotive applications using our M-FORCE® SD500 Variable Frequency Drives. Magnetek can also provide custom monitoring, data collection and display systems integrated with any Magnetek M-FORCE® SD Drive to provide the ultimate in assured performance and control. Our flexible building block approach allows us to configure a custom display and controller to your exact requirements. The control interface provides real-time diagnostics for preventative maintenance and troubleshooting, reducing down time and repairs.


Adjustable operating speeds, torque limits, and controlled stopping allow for smooth operation and torque control from stall to 400 Hz.


A custom engineered system can improve the power factor and reduce in-rush currents to minimize energy consumption.


Controlled start-up torque decreases the wear and tear on the motor and connected load, which reduces mechanical breakdown to extend motor life.
