WHAT I KNOW AND ACTS M2

• Torque - the measure of how much strength the motor outputs
• An electric motor changes electrical energy into mechanical energy
• A stepper motor is a/an incremental device
• The higher the speed a motor has, the lower its torque
• A stepper motor is a/an open loop system
• A servo motor is a/an closed system
• The rotational speed of a given stepper motor is determined solely by a step pulse frequency
• Lead screw is NOT a type of stepper motor
• The hybrid stepper is designed to promote maximum power
• The gear of a servo motor is mainly made of plastic
• 180 degrees - what degree does the positional rotation servos limited in motion
• Positional and continuous - two basif types of servo motors
• Servo motors operate under a constant closed loop feedback mechanism as opposed to the open loop system of a stepper motor
• ST - It has multiple “toothed" electromagnets arranged around a central gear-shaped piece of iron
• SE - A DC motor that allows for precise control of the angular position
• ST - It has a controller system that sends electrical pulses to a driver
• SE - This motor can provide very precise motion control
• SE - It has a maximum torque at low speeds
• Stepper motor is generally less expensive than a comparable servo motor
• A stepper is a/an open loop system
• A servo is a/an closed loop system
• A servo has higher torque at higher speed
• Stepper motors cannot run at high speeds, but have a high holding torque.
