Brake Motors

More Information about Brake Motors

Baldor-Reliance Brake motors are available in single phase and three phase designs utilizing footed or footless mounting provisions. They have the spring-set brakes mounted opposite the drive end, allowing a NEMA-standard BA dimension. Brake coils are connected inside the conduit box for easy access for separate connection when used with a variable speed drive.

It's worth noting that the availability and specific features of brake motors may vary depending on the manufacturer and region. For more detailed information and to explore specific brake motor options, it is recommended to consult the website or contact authorized suppliers and manufacturers specializing in motor products.

FAQs

What is a common site where brake motors are successfully used?

A common site where brake motors are successfully used is in conveyor systems. Conveyors are widely used in various industries, such as manufacturing, distribution, and material handling, to transport goods and materials.

To select the appropriate brake motor for purchase, what added features should a customer look for?

When selecting a brake motor for purchase, there are several added features that customers should consider. These include: safety features, brake performance, application compatibility, Totally Enclosed Fan Cooled (TEFC), protection and easy access.

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.
