Question 490Electricity & Electronics - QMED
70% to passWhat type of DC motor is never connected to a belt driven load?
Aseries wound
Bshunt wound
Ccompound wound
Dpermanent magnet
AI Explanation
The correct answer is A) series wound. Series wound DC motors are never connected to a belt-driven load because they are not suitable for that application. Series wound motors have a high starting torque but poor speed regulation, which means their speed can vary significantly with changes in load. This makes them unsuitable for driving a belt-driven load, as the varying speed could cause instability or damage to the belt and driven equipment. The other options, shunt wound (B), compound wound (C), and permanent magnet (D) motors, are better suited for belt-driven loads due to their more stable speed characteristics.
