PERFORMANCE CONTROLS, INC.®
Sensorless Motor Drive for Harsh Environment
PERFORMANCE CONTROLS, INC. ® DHT-24 amplifier is a 3 phase motor drive that employs a proprietary Sensorless control algorithm to drive a Brushless DC motor (BLDC) that runs from a 24VDC input. However, perhaps the most important feature is that it does all this at 175C. When operating thousands of feet below ground the last thing a service provider wants is to have their drill stop because of a component failure, particularly with the high financial and reputation costs associated...

Celeroton
Electronics for sensorless speed control
Due to an integrated design approach, highest compactness and efficiency of the converters and minimal losses in stator and rotor of the motor are achieved. All converters allow for sensorless speed control without encoders or hall sensors up to highest speeds of permanent-magnet synchronous machines (PMSM) as well as brushless DC motors (BLDC). No output filter is required due to the employed PAM-technology. (read more)

Celeroton
Sensorless speed control with the new CC-75-500
Celeroton launches the converter cc-75-500 as the world`s first devide that allows for sensorless control of permanent-magnet synchronous machines (PMSM and BLDC) from zero up to 1 million rpm. The emloyed PAM-technology enables the control of BLDC and PMSM wuth higher rotational speeds and minimal losses in stator and rotor. Due to the sensorless speed control no hall sensors or encoders need to be integrated in the motor anymore. With this approach, a simplified motor design is achieved... (read more)
