摘要： A coring bit, including an outer hollow coring shaft, and a rotationally uncoupled internal sleeve disposed inside the outer hollow coring shaft. The rotationally uncoupled internal sleeve may be a non-rotating internal sleeve. The rotationally uncoupled internal sleeve may be a free-floating internal sleeve.

摘要： Disclosed is a system and method for controlling a clutch associated with a solenoid using a pulse width modulated (PWM) signal, which keeps the current through the coil constant over a wide temperature range and fluctuations in line voltage. The system may include a voltage source, a switch (such as a FET), a current sensor, and a processor. The system controls the clutch by sampling the voltage source, sampling the current measured by the current sensor, and computing a duty cycle, which is then used to generate a PWM control signal.

摘要： A system and method of controlling motor temperature is based on computed motor power dissipation and a thermal model of the motor, rather than a measured motor temperature, in a control loop that limits the motor drive to prevent overheating. An ambient temperature sensor senses the ambient temperature near the motor, and a determination is made of the motor power dissipation. The motor winding temperature is estimated based on the sensed ambient temperature and the determined motor power dissipation. A maximum motor power dissipation that would raise the motor temperature to a predetermined maximum temperature value is determined based on the estimated temperature. The motor power dissipation is limited to a value that is below the determined maximum power dissipation.
