DHT56-05 Down-Hole Drive
The DHT56-05 Downhole Motor Drive from Performance Controls, Inc. (PCI) is a fully digital motor controller designed for long life in harsh environments in down-hole applications such as Directional Drilling, Horizontal Drilling, MWD, LWD, and Wireline. The amplifier can control a BLDC servo motor in torque or velocity loop mode and can be digitally configured for a wide range of motors.
For Brush, BLDC Motors
56 VDC, 3 A Continuous, 5.1 A Peak
350 deg F (175 deg C) Operation
Fully Digital
Applications
The DHT56-05 Downhole Tool Motor Drive can be used in these and other applications:
- Directional and horizontal drilling
- MWD (Measurement While Drilling)
- LWD (Logging While Drilling)
- Wireline
Features and Benefits
High Temperature Operation
Independently tested to operate at 350 deg F (175 deg C)
Ruggedization
Enables survival under the shock and vibration conditions associated with down-hole services.
Small Size
17 x 1.85 x 0.10 inches (432 x 47 x 2.6 mm) for the PCB.
Sensorless Control
Increases reliability and reduced overall packaging through elimination of failure-prone Hall sensors and bulky cabling.
Power Saver Mode
Extends the life of the battery when activated.
Advanced Commutation
Space Vector Commutation and Flux Vector Current Control improve bus voltage utilization for improved torque/speed curves, improved energy efficiency, and reduced heat dissipation.
Digital Tuning
Optimizes performance, enables cloning, eliminates pot drift, and reduces inventory through the use of the same drive for multiple applications.
Programmable
Allows adjustments to start-up current limit and ramp rate, and other parameters.
Extensive Fault Protection
Protects the amplifier and the motor, and can be individually programmed by the OEM.
Customization
PCI can modify the drive to make it compatible with an OEM’s system.
