Marotta Introduces New DC Brushless Sensorless Motor Controllers 

Marotta’s Electronic Brushless Sensorless Motor Controller incorporates the latest technologies with proven high-voltage motor drive and closed loop servo techniques, resulting in a cost effective system with minimum risk and rapid development in your system.       

Benefits of DC Brushless Sensorless Motor Controllers  

The motor controller design is configurable for two or four quadrant operations and embraces all functions necessary to support motor drive and speed regulation, input power interfaces, input control signals and output status reporting signal interfaces.  DSP technology is used for precise repeatable control and ease of tailoring for each application's load type and dynamic response requirements.  

The small size and light weight of the Marotta DC Brushless Sensorless Motor Controller is ideal for aerospace and military applications. 

Key Features   

• DC Brushless Motor Controller provides constant or variable speed control.  

• Sensorless operations reduces overall system cost and weight while increasing reliability. 

• DSP digital dual-servo control offers stable servo performance 

• PID Algorithms tailorable for specific motors and loads

• Thermal management flexibility based on the application

• Analog/discrete or serial vehicle control interface 

• Built-in test (BIT) diagnostics 

• Motor drive circuits use efficiently packaged Isolated Gate Bipolar Transistors (IGTBs)

• Built-in low voltage power supply provides single supply operation. 

• PWM motor driver amplifier for optimum power conversion efficiency. 

• Input power - 270 vdc input power 

• Output power - up to 5 kw

• Weight - 7 lbs at 5 kw; commensurately smaller for lower power applications. 

• Size - 6" x 2.5" x 9" at 5 kw; commensurately smaller for lower power applications. 

• Designed to meet MIL-STD-461E
