A VFD (Variable Frequency Drive) is used to regulate the speed of a 120V single-phase motor. It controls the motor's output speed by changing the power supply frequency, adapting to different load requirements, reducing starting shock, and extending the motor's lifespan.

Application
Agriculture and Irrigation: VFDs are used to drive water pumps with 120V single-phase motors, regulating pump speed and water flow to meet different irrigation needs.
Home Appliance Applications: VFDs are used to control the compressor and fan speeds of home appliances (such as air conditioners and refrigerators) with 120V single-phase motors, regulating the operating load.
Industrial Equipment: VFDs regulate the speed of industrial equipment (such as small pumps, fans, and conveyor belts) driven by 120V single-phase motors to meet production needs.
Power Tools: VFDs are used to drive the speed of power tools (such as electric drills and cutting machines) with 120V single-phase motors, adjusting power output according to the workload.

FAQ
Q: Do you supply pattern ? Is it free?
A: If the pattern is low value, we will grant the free pattern with freight collect. But for some excessive fee samples, we want to gather the pattern charge.
Q: What is your time period of payment?
A: 30% down charge earlier than producing and 70% stability charge earlier than shipping.
Q: Can a VFD be used directly with a 120V single-phase motor, or is additional equipment required?
A: A VFD can be used directly with a 120V single-phase motor. It controls the motor speed by adjusting the input voltage and frequency, requiring no additional equipment. When selecting a VFD, ensure its rated voltage matches the motor's.
Q: What changes will occur when starting a 120V single-phase motor using a VFD?
A: A VFD makes the motor start smoother, employing soft-start technology to reduce starting current, lower mechanical shock, and reduce the burden on the motor and electrical system.
Q: Can a VFD regulate all types of loads on a 120V single-phase motor?
A: A VFD is suitable for most common loads, such as fans, pumps, and small machinery. However, for some loads requiring high starting torque, a specially selected appropriate VFD model may be necessary.
Q: Will using a VFD extend the lifespan of a 120V single-phase motor?
A: A VFD helps extend the motor's lifespan by reducing starting current and controlling operating speed, thus reducing motor wear and overload risk.
