# Which motor gives high starting torque?

Contents

## What motor has the highest starting torque?

The torque of the DC series motor is proportional to the square of the armature current. That is why the DC series motor has high starting torque. The DC series motor produces the highest torque among all kinds of motors.

## Which has high starting torque?

DC Series motors have high starting torque but induction motors have wide range of speed control.

## What is starting torque of DC motor?

Starting torque is the maximum torque that can be produced by a motor in order to start rotational movement of the load. Stall torque is the maximum torque that can be applied to the shaft and cause the motor to stop rotating. When there is no rotation in the motor, the wound coils are acting as a fixed resistance.

## What is startup torque?

Starting torque is the torque transferred by the shaft coupling during run-up (see Start-up process). It is calculated based on the ratio of power (P) to angular velocity (ω) and is represented as a rotational speed function.

## Which motor has high starting torque AC or DC?

DC motor has high starting torque.In a series motor the same current flows through the armature and the field winding. The torque is therefore proportional to the square of the current. The current is set by the supply voltage and the back-emf generated in the armature.

## Why do series motor have high starting torque?

Torque. Series motors have the characteristic of developing very high starting torques. The reason for this is the same current that passes through the armature also passes through the field windings.

## Does induction motor have high starting torque?

Slip ring induction motor has high starting torque. Because slip ring is connected through the resistance. When the supply is on the resistance is increases the phase difference is decrease due to this starting torque is increases.

## Is starting torque higher than full load torque?

At locked rotor and maximum torque, the current is quite high, in the area of 5 or 6 times rated current. That is why both start up torque and maximum torque are higher than full-load torque.

## What is DC motor stall torque?

Stall torque is the torque available from a motor whose output rotational speed is zero. Motors in a stalled condition may be prone to overheating and possible damage if the current flowing under these conditions becomes higher than the maximum continuous rating.
