Such as the impact of the water pump, when the pump stops suddenly, the water flow Types of Soft Sot Various reduced voltage starting options have been available. Abstract Most of the water supply schemes use electrical power in large quantities.

Kanti, your observations are very correct, 20 years back this was the only easily manufacturable solution with transformer like structure and cheap.

The MC winding is magnetically coupled to the main winding and ER winding. The advantage is to have low voltage compensators which are in a close circuit with the MC winding so immediatly discharged when not used. 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.

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 As the motor speed increases the FCMA impedance decreases to achieve incremental voltage and torque for the motor while keeping the current constant.

Claims of this technology are zero harmonics in power. A built-in bypass contactor closes to ensure full voltage running of the motor.

Possibility to reduce in some case the starting current on the grid to: Soft starters have no Hz regulation capabilities. ER and MC options are designed to reduce stafter line current down to 1.

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 Products Contact us China soft starters manufacturer Softstarter gozuk.

And in maruti suzuki a renowned automobile company in India Working fine for more than 20 years To further reduce the line current, MC winding could be used. The magnet is provided with a retentive core so that even in the event of control supply failure the magnet opens only after 0.

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.

No special protections are required for soft starters. This leads to saving in transformer capacity and fcmw. Closed transition hence no momentary disconnection of supply.

Conventional motor protections are sufficient. The softest start for your electrical motor, with a constant, stepless acceleration and without harmonics. As the net flux is sinusoidal the FCMA does not generate any harmonics. 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. FCMA soft starter are stepless voltage reducing starters which ensure a constant low starting current with incremental voltage and torque to the motor to achieve a continious and smooth acceleration of the drive.


Thanks tambe I will read his over the weekend, mag amps were big things some time ago, then came semiconductors. FCMA is totally non-saturable and hence does not generate any harmonics. Soft starter setting Soft starter allows the output voltage decreases gradually to achieve soft stop, in order to protect the equipment.

FCMA Soft Starter

Advantages Staretr starting on limited power source, smooth starting and acceleration. This current is in phase opposition to the motor current and hence will directly be deduct to the line current.

Available electronically from http: Why bunkering pump motor trip in the morning? Posted by Hitesh Vadnagare at 3: Natural Side Soft Starters. The motor current is kept constant due to the balancing effect of Cemf feedback. Main features of Soft Starter These are the main features and benefits of soft starter:
