What is the difference between a scalar and a vector VFD?
A. Scalar VFDs use simple mathematical algorithms to control the speed of the motor, while vector VFDs use complex mathematical algorithms
B. Scalar VFDs can only control the speed of the motor, while vector VFDs can also control the torque of the motor
C. Scalar VFDs are typically less expensive than vector VFDs
D. Scalar VFDs are typically used for applications with low starting torque requirements, while vector VFDs are typically used for applications with high starting torque requirements.
Answer:B
What is the difference between a scalar and a vector VFD?
A. Scalar VFDs use simple mathematical algorithms to control the speed of the motor, while vector VFDs use complex mathematical algorithms B. Scalar VFDs can only control the speed of the motor, while vector VFDs can also control the torque of the motor C. Scalar VFDs are typically less expensive than vector VFDs D. Scalar VFDs are typically used for applications with low starting torque requirements, while vector VFDs are typically used for applications with high starting torque requirements.
Explanation: Scalar VFDs use simple mathematical algorithms to control the speed of the motor, while vector VFDs use complex mathematical algorithms to control both the speed and torque of the motor. Vector VFDs provide a higher level of control over the motor, making them better suited for applications with high starting torque requirements. Scalar VFDs are typically less expensive than vector VFDs and used for applications with low starting torque requirements.
