Submersible Motors

Submersible motors are a key product in various water supply applications. Designed for a variety of uses, these motors are especially critical in pumping water from deep wells and other submerged locations.
The Baldor submersible motors, for instance, are renowned products in this field. Designed with specific features in mind, they cater to an extensive range of applications. These motors are built to withstand high voltage use, ensuring minimal risk of failure.
One of the notable features of these motors is their canned type design. This refers to a hermetically sealed, fully submerged design where the motor and the pump are compactly integrated. It's a particularly beneficial feature in water-related applications as it prevents water from entering the motor, thus reducing the chance of motor failure.

More Information about Submersible Motors
Submersible motors are made of cast iron, a material known for its strength and durability, which is essential for their long-term performance in challenging underwater environments. The size of these motors can vary depending on the requirements of the application, offering customers a variety of product choices.
By contacting authorized dealers, customers can learn more about these motors, providing them with the necessary product information to make informed decisions. It is also a chance to touch base with experts who can offer guidance based on specific water supply needs.
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.
