Motor Controls

Bay Breakers is home to a comprehensive inventory of electric motor controls from the biggest brand name manufacturers in the business. Our warehouse is packed with quality new, used, and hard to find obsolete units from leaders like GE, Westinghouse, Siemens, Cutler Hammer, and Federal Pacific (FPE).

These controllers are essential to a host of electrical applications and industrial processes. They are used to govern many crucial aspects of performance of electric motors. Some controls start or stop a motor either manually or automatically. An example of a manual motor control would be the control switch for a bathroom fan. Other motor controls create changes in forward or reverse rotation, regulate motor speed, limit the degree of torque, or guard against circuit overloads.

A motor control center or an industrial drive consists of a bank of controllers working together to govern multiple motor functions or coordinate the actions of several motors working together. Arrays of motor speed controls, along with other electrical components become the mechanical brain of every commercial and industrial process control application.

The choice of controller for the job is dependant upon the type of motor needing governance, the operating current, and the functions it needs to perform to accomplish its purpose. Bay Breakers provides both ac and dc motor controls for servo motors, single phase motors, brushless dc motors, and three phase motors. Rugged and reliable name brand units from General Electric, ITE, Square D, and Westinghouse include:

Modern stepper motor controls that drive motors with much higher voltages than the rated voltage on the tag and limit current through chopping. These can be used in pairs with a positioning controller (the indexer) sending pulses to another stepper controller that governs commutation and current limiting.

PWM motor controls utilize ‘Pulse-Width Modulation’ to regulate current sent to the motor. They produce smoother current at higher switching frequencies than many other types of controllers.

Servo controllers are a wide and versatile category of industrial controls. Some of the main features of this line of components are fast acceleration rates; precise closed loop position control; and precision speed control. These controls may utilize pulse-width modulation or a pulse and direction method for motor governance.

SCR Controllers are for governance of dc motors and are very common in the industry. These robust and dependable dc motor controls have a minimum of electronic components, run from standard 120V or 240V line voltages, and rarely need maintenance. Bay Breakers Online stocks GE, Siemens, and Cutler Hammer models in both reversing and non-reversing configurations along with other complementary products such as mcc buckets, safety disconnect switches, and bus plugs.

Induction motor controls have seen many advances in efficiency and speed control over recent years and Bay Breakers Online features several high performance new and professionally reconditioned models for your next important induction control application. These motors operate by using electric current to induce rotation in the coils. Induction motors are the most common industrial AC motors and the newer controllers has made it possible for ac induction motors to compete where formerly only a dc motor could do the job. Several varieties of name brand induction motor controls are available from Bay Breakers Online including variable frequency controls, phase vector drives, and direct torque controllers from General Electric, Westinghouse, and ITE/Siemens.

Bay Breakers Online is the place to find the perfect motor control for every application. Check out our enormous online inventory of leading name-brand controllers, circuit breakers, motor starters, and heavy-duty air circuit breakers at the very best prices in the business.
