DC 3 Point starter suitable for 2 to 5 HP rated DC Shunt Motor Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-13118
Indian Lab Suppliers supplies the DC 3 Point starter suitable for 2 to 5 HP rated DC Shunt Motor (Product ID: 13118) as part of its electronics engineering lab equipment range. It is a 3-point starter for DC shunt motors rated 2 to 5 HP on a 220 V DC supply.
Quick Answer
At standstill a DC motor has no back emf, so full voltage across its low-resistance armature would draw a very large current. The starter puts resistance in series with the armature and cuts it out step by step as the motor speeds up and back emf builds. In a 3-point starter the hold-on (no-volt release) coil is in series with the shunt field, so the handle returns to OFF if supply or field current is lost. Its three terminals are line, field and armature.
