A built-in bypass contactor closes to ensure full voltage running of the motor. The softest start for your electrical motor, with a constant, stepless acceleration and without harmonics.

FCMA Soft Starters

Available electronically from http: The FCMA works on the principle of superimposition of sinusoidal fluxes on a common magnetic core where the net flux is the vector sum of the two components.

Unique FCMA technology, Low starting current, Amplitude control, Sinusoidal Waveform, Rugged magnetic design No harmonics, No maintenance, Suitable for extreme weather conditions, Built in bypass for full voltage, Run Indoor and outdoor models Line or neutral models available, Optional soft stop feature.

Additionally the Genset will run at optimum load and efficiency, leading to fuel saving. The large pumps, in many water systems, are driven by induction and synchronous motors.

To summarize, Soft Starters can optimize the starting performance of motors and motor manufacture can concentrate on improving running performance to ensure lower life cycle costing. An additional coil protection relay is provided for additional safety. The MC winding is magnetically coupled to the main winding and ER winding.

As the motor speed increases the impedance of FCMA reduces steplessly to keep the current constant and increase the motor torque so that the load is accelerated.

The fraction of energy that can be tapped is proportional to the voltage drop in the FCMA module and the motor current. This technology has been successfully implemented for about MW motor power in the pumping sector. It also assists in enhancing motor efficiency. The use fmca FCMA helps in optimizing power systems, increasing the life of components and reducing the capital cost and maintenance expenditure of pumping systems.

Thursday, May 13, Blogger Buzz: Even known as magnetic ffma or series reactor soft starter.

Customized starting on limited power source, smooth starting and acceleration. The voltage across the motor increases smoothly from starting to run value with motor speed. The advantage is to have low voltage compensators which are in a close circuit with the MC winding so immediatly discharged starterr not used.

B] Transformer starting Considerations — Transformer p. Follow us on Twitter Youtube. Flux Compensated Magnetic Amplifier soft starters are step less reduced Voltage starters which ensure a constant low starting current with incremental voltage and torque sofy the motor to achieve smooth acceleration of the drive.

They can boost current and voltage at start, but it’s a voltage boost to initiate movement if the motor bogs at start, after which the boost voltage Soft starters have no Hz regulation capabilities.

As such, optimization is needed for reducing life cycle cost of the entire establishment in terms of capital cost, minimum downtime, and maximum availability.

Does soft starter suitable for crane? It can also optimize total power system. Thanks tambe I will read his over the weekend, mag amps were big things some time ago, then came semiconductors. Why bunkering pump motor trip in the morning? Product Support Services Forum mySupport.

Working Principle Flux Compensated Magnetic Amplifier soft starters are step less reduced Voltage starters which ensure a constant low starting current with incremental voltage and torque to the motor to achieve smooth acceleration of the drive. No forced cooling required. The motor current is kept constant due to the balancing effect of Cemf feedback.

MV / HV FCMA Soft Starter

Types of Soft Starters Various reduced voltage starting options have been available. Site Explorer Site Explorer. The FCMA is connected in series with the motor either on the line or neutral side, so that the starting current is limited to a low value. Collections Turbomachinery and Pump Symposia.

It srarter also important to avoid disturbances in the power system in terms of overloading and other harmful effects like voltage and frequency dips and harmonics. Closed transition hence no momentary disconnection of supply. Higher motor life due to reduced Mechanical and Electrical stresses, Capital cost saving in power systems.

The FCMA main winding is in series with the motor and drops a voltage across itself to limit the motor voltage and motor current. Such as the impact of the water pump, when the pump stops suddenly, the water flow Metadata Show full item record.

FCMA Soft starter The softest start for your electrical motor, with a constant, stepless acceleration and without harmonics. Blogger integrates with Amazon Assoc The values of starting current can be adjusted strater site and six such adjustments are provided. An aggregate of approx. Bypass contactor srarter can be time, Current or speed based.

The soft starter is connected in series with the motor either on the line side or neutral side and thus, controls the starting current and starting torque. Kanti, your observations are very correct, 20 years back this was the only easily manufacturable solution with transformer like structure and cheap. I have talked to many users they are satisfied with FCMA technology as it requires nearly no maintenance This is innovative technology for incremental motor voltage and torque at constant reduced current.

A built-in bypass device closes to ensure full voltage running of the motor after starting, bypass operation can be time, current or speed based.
