Soft Starter Panel | Motor Starting & Soft Control System
Specialized design and manufacturing of soft starter panels for smooth starting,
starting current control, and reduction of electrical and mechanical stresses on electric motors in industrial projects.
From engineering and design to soft starter selection, protection equipment, control circuits, wiring, testing, and commissioning, tailored to the specific needs of each project.
What is a Soft Starter Panel?
A soft starter panel, or
Soft Starter Panel,
is designed and built for the smooth startup of electric motors and to reduce the current and stresses caused by direct motor starting.
By gradually controlling the voltage applied to the motor, the soft starter makes the starting process—and in many models, the stopping process—smoother, helping to reduce mechanical shocks and electrical stresses during startup.
In addition to the main device, a soft starter panel includes protection breakers, necessary contactors, control and command equipment, bypass provisions where required, a ventilation system, and accessories necessary for safe and stable motor operation.
Gradual increase of motor voltage for controlled starting and reduced initial shock.
Reduction of mechanical shocks during motor startup and on connected equipment.
Limiting and controlling motor starting current compared to direct online starting.
Mitigating the adverse effects of large motor startups on the power grid under appropriate conditions.
Using a soft starter provides controlled motor starting and reduces stresses caused by direct starting in suitable applications.
Reduction of shock and stress from direct motor starting and creation of controlled starting.
Ability to use appropriate protection for the motor and power circuit based on design.
Control of starting current and mitigation of its impact on the network under proper conditions.
Reducing mechanical stresses during startup can help extend the life of connected equipment.
Panel equipment is selected based on motor power, rated current, load type, starting frequency, ambient conditions, and project requirements.
The core panel device for controlling the starting process and, if supported, smooth stopping of the electric motor.
Use of MCCB, MCB, or appropriate protective devices to protect the input circuit and motor based on design.
Main contactor and appropriate switching equipment matching circuit design and soft starter requirements.
Use of internal or external bypass, as needed and according to design and soft starter capabilities.
Protective relays, overload protection, and other required safeguards based on motor type and system design.
Push buttons, selectors, indicator lights, control relays, and other equipment required for motor control and command.
Capability to connect the soft starter to PLC, HMI, and monitoring systems for advanced control and supervision.
Fans, filters, thermostats, and ventilation equipment for controlling internal panel temperature as needed.
Enclosure design, IP rating, dimensions, ventilation, and equipment access based on installation environment and project requirements.
Final specifications are determined based on motor power and current, load type, starting frequency, network conditions, ambient conditions, and project requirements.
