Solid state motor control. Solid State Motor Control Eaton offers a wide range of VFD products and soft starters to meet a wide array of applications from simple variable torque controls to more complex industrial applications such as conveyors mixers and machine controls. The S511 device is a semiconductor reversing contactor designed to switch three-phase motors forward and reverse. Unicore electronics and thermal design ensures high switching capacity and long lifetime.

The LED is illuminated solid green when control power is present and with the proper polarity yRUN LED This LED is illuminated solid green when a start command and control power are present yNETWORK LED This bicolor redgreen LEDs indicates the status of the communication link yFAULT LED Indicates Controller Fault trip condition. A solid state motor speed control is described that is capable of controlling a motor so that it operates quietly eliminating annoying buzzing noises that would otherwise be generated by the motors windings. The invention provides for motor speed control with infinitely variable speed control settings.

Motor control has always been something difficult to tackle with as a motor is first of all an inductive type of load with high starting currents which doesnt help reduce size and costs of protection devices like fuses and over voltages generated at turn-off. This is why Solid State solutions are more and more popular to control motor loads. DC Motor EquationsDC Motor Equations where J D and TL are the moment of inertia damping factor and load torque Dynamic Steady- State.

A solid-state controller determines to what degree the SCRs should be triggered on to control the voltage current and torque applied to a motor.

A solid-state controller also includes current-limiting fuses and current transformers for protection of the unit. Saftronics Solid State Motor Control VFD - Steep Hill Equipment Solutions. A solid state speed control contains components such as triacs which are semiconductor devices with no moving parts which can control the flow of current to a device.

They are useful because they can be controlled quite precisely to turn on and off at specific parts of a waveform. Trol systems solid-state logic controls or program-mable logic controllers PLCs. The fundamentals of control systems still apply.

The PLC controls an exter-nal output based on the logic of a control program and that output controls the motor or groups of motors by using a magnetic starter and in some cases additional relays.

These controllers include load break switches that provide integrated intelligence and the lowest-cost solution for starting motor applications. One important advantage of specifying a motor control rated Solid State Relay or Solid State Contactor is that the agency approval process for the end application is greatly simplified and further costs associated with approval of the motor control which can be substantial are born by the Solid State Control supplier Crydom in this case.

All hardware software sensors and accessories are designed and built to work as a single integrated system eliminating coordination and performance issues inherent in systems compiled from dissimilar third party components. With a comprehensive set of standard hardware features hundreds of available engineered. A Solid State Relay SSR is a re lay that does not have a moving contact.

In terms of operation SSRs are not very different fr om mechanical relays that have moving contacts. SSRs however employ semiconductor switching elements such as thyristors triacs diodes and transistors. With over 38 years of specializing in the manufacturing of solid state AC motor controls and motor protection products Motortronics is a world-wide leader second to none.

Having shipped millions of solid state starters and controllers to virtually all industries around the world we have amassed more real world experience than any other. Classified as solid state relays even though they meet the litmus-test criteria established above for classification as solid state contactors. This has nothing to do with the operation of the products as they perform the exact same function of a solid state contactor.

Solid-state relays have a phase control option which is ideal for motor-speed con-trol and light-dimming applications. Figure 17-3 shows control of a fan using a solid-state relay SSR. RELAY PWM DC AND STEPPER MOTORS639 Table 17-2.

The latest generation of soft starters and Smart Motor Controllers SMCs offers significant advantages over its predecessors when it comes to using it in wye-delta applications. In most cases you can use these solid-state products to replace or retrofit any of the traditional reduced-voltage methods. Magnetic contactors Magnetic starters.
