## How do you select a motor on the basis of torque?

The higher the voltage, the higher the torque. The voltage rating of a DC motor indicates the most efficient voltage while running. Be sure to apply the recommended voltage. If you apply too few volts, the motor will not work, whereas too many volts can short windings resulting in power loss or complete destruction.

## How do you select a motor for a particular application?

A constant or variable torque and horsepower will be required for the industrial motor depending on the type of load the motor is driving. The size of the load, the required speed, and acceleration/deceleration—particularly if it’s fast and/or frequent—will define the torque and horsepower that is required.

## Which motor is constant speed?

A DC motor can be referred to as a constant speed motor because it can self- regulate its speed.

## How do you select a pump motor?

When choosing a motor for a centrifugal pump, you must consider the impeller size, maximum capacity, specific gravity of the fluid, and service application in case API requirements apply. If you take these things into account, you will select the right motor for your centrifugal pump application.

## How do you choose RPM for a motor?

How to Calculate Motor RPM. To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM.

## Is it better to have more torque or horsepower?

Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. Horsepower is how rapidly the vehicle can perform that work. … Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.

## Does higher torque mean faster acceleration?

In terms of acceleration, torque plays a bigger role in how quickly your car accelerates. That’s because the torque is a result of the force the pistons generate and at what speed. The quickest vehicles can generate high levels of this torque force at relatively low rpm. This allows the vehicle to accelerate quickly.

## Which induction motor has maximum speed?

Synchronous and full load speed of amplitude current (AC) induction motors

Speed (rpm)
Number of Poles Frequency (Hz, cycles/sec)
