- Datalogger: A device or software that continuously records data over time, such as temperature, voltage, or current, for analysis or diagnostics in industrial systems.
- DC motors: Motors powered by direct current, commonly used where precise speed control is needed. They offer good torque at low speeds and are found in automation, robotics, and battery-powered systems.
- Deceleration ramp: A programmed or controlled reduction in motor speed over time, used in drives and motor controllers to prevent mechanical stress or abrupt stops.
- Deceleration time: The actual time it takes for a motor or system to slow down to a complete stop; can be controlled electronically via a drive.
- Delta circuit: A three-phase wiring configuration where the ends of each phase coil are connected in a triangular (delta) shape, allowing full line voltage across each winding.
- Dielectric constant: A material property indicating its ability to store electrical energy in an electric field. It affects insulation performance and capacitance.
- DIL contactors: A specific line of modular contactors from Eaton, designed for compact installation, motor control, and integration with auxiliary devices.
- Direct motor start: A simple starting method where the motor is connected directly to the power supply, allowing immediate full-voltage startup.
- DOL starter (Direct-On-Line starter): A type of motor starter that connects the motor directly to the line voltage, typically including a contactor and overload relay. It’s simple but can cause high inrush current.
- Double-frame terminal: A terminal design that uses two clamping frames to ensure secure connection of conductors, improving safety and contact reliability.
- Drive system: An electronic or electromechanical system used to control the speed, torque, and direction of an electric motor. Commonly includes frequency converters or variable speed drives.
