Compressor Duty Motors
Compressor duty motors are electric motors that are specifically designed for use in air compressor applications. These motors are typically designed to run continuously for long periods of time, and are capable of providing the high torque requirements needed to start and run compressor pumps.
Compressor duty motors are used in a wide range of air compressor applications, including stationary air compressors and portable air compressors. These motors are typically more durable and reliable than standard electric motors, and are built to withstand the high temperatures, vibrations, and other stresses associated with compressor operation.
In addition to it's high torque and durability, a compressor motor can also offer other features that make it well-suited for air compressor loads. For example, some models may have built-in thermal protection to prevent overheating, or may be designed for easy mounting on compressor pumps.

Motor Starters, Soft Starters and VFDs
Motor Starters
Motor starters safely start and stop a motor in industrial applications. They are designed with a contactor, overload and circuit protection. They are used when basic motor control is required, where torque on the motor is not a concern and speed control is not needed. The advantages of motor starters include: lower cost, allows for remote operation, allows for monitoring of motor state (with the use of auxiliary contacts) and they are safe and efficient. The disadvantages include: high inrush current that can cause fuses to blow and breakers to trip if the inrush is too high, and the starter will allow a full torque to start the motor which can cause the motor to ramp up to full speed very quickly potentially causing the motor to wear and degrade prematurely.
Soft Starters
Soft starters protect motors from inrush current by gently ramping up the motor to full speed. They provide all of the same functions as a traditional motor starter. The advantages of soft starters include: they are less expensive than a VFD when only startup control is needed, they are a smaller system than a VFD where space is a concern and they prevent unwanted torque upon startup, prolonging the life of the motor. The disadvantages include: they are more expensive than a traditional motor starter and they do not allow for full speed control.
VFDs
A Variable Frequency Drive (VFD) allows for the slow ramp up of a motor during startup and the slowing down of the motor during shutdown. It also allows for full speed control during the entire run cycle of the motor. VFDs provide the same functions as both the traditional motor starters and soft starters. The advantages of VFDs include: full speed control (start, stop and in-between), more custom control and monitoring, energy savings due to efficient motor usage and less wear and tear on the motors. The disadvantages include: they are more expensive and larger than other motor control options and they generate heat that may require fans or AC units.
