Motor-Drive Option At the Society for Neuroscience 2000 Convention in Miami, Dragonfly R&D, Inc. introduced a motor-drive that dramatically reduces the amount of force required to turn the commutator. A torque-sensor detects rotation, activating a precision stepper motor that turns the unit until proper positioning is achieved. Our unique position sensor design requires only one commutator channel to detect clockwise, counter-clockwise, and stationary states. Extremely low sensor current minimizes electrical noise that can potentially affect sensitive data channels. A motor speed control is provided to optimize positioning time. Two different motor sizes are used to make this torque-sensing motor drive an option with any of our slip-ring commutators. |
