DC 4 Point starter suitable for 2 to 5 HP rated DC Compound Motor Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-13120
Indian Lab Suppliers supplies the DC 4 Point starter suitable for 2 to 5 HP rated DC Compound Motor (Product ID: 13120) as part of its electronics engineering lab equipment range. It is a 4-point starter for DC compound motors rated 2 to 5 HP on a 220 V DC supply.
Quick Answer
Like the other DC starters, it limits armature current at starting with resistance that is cut out as the motor accelerates. The difference is the fourth terminal: the hold-on coil is connected across the supply through its own resistor rather than in series with the field. Field current can therefore be reduced with a field regulator to raise speed without tripping the starter. It is used with compound motors and with motors whose speed is controlled by field weakening.

Where This Is Used
Used in speed-control experiments on compound motors; compare with DC 3 Point starter suitable for 2 to 5 HP rated DC Shunt Motor (Product ID: 13118). Starters work at 220 V DC with live contacts: mount them on an earthed panel, switch off before wiring and never force the handle past a step.

Frequently Asked Questions
How does it differ from a 3-point starter?
Its hold-on coil is independent of field current.
Which motors does it suit?
DC compound motors of 2 to 5 HP.
Why does that matter?
Field weakening for speed control will not release the handle.
