The maximum load current is the maximum continuous current that can be used to continuously drive a load, If the current is higher than that, the motor will run too hot and the insulation will fail eventually. Exceeding the maximum load current slightly will reduce the lifetime of the motor slightly.

## What is load in motor?

The term “load” can also mean “**the amount of power” or “the amount of current” drawn by the thing that is connected to the output of the circuit**. The load can basically be anything. For example, it can be a resistor, or a capacitor or an inductor, or a transistor, or a motor, or an air conditioner etc.

## What is meant by no load in DC motor?

DC SERIES MOTOR have field and armature windings connected in series and both carry same current so, For no-load, which means. As **field current is zero so field flux becomes zero**. As speed of a motor is inversly proportiona.

## What is load characteristics of DC motor?

Characteristics of different types of load: In electric drives the driving equipment is an electric motor. … **Torque proportional to speed (generator type load)** 3. Torque proportional to square of the speed (fan type load) 4. Torque inversely proportional to speed (constant power type load) 1.

## What type of motor load is the most commonly used?

2. **Quadratic torque**. **Quadratic** torque is the most common load type.

## Which motor has highest no load speed?

Explanation: At no load, armature current tends to zero, flux φ tends to zero, where speed is inversely proportional to the flux, speed will tend to infinity. Thus, no load speed of **DC series motor** is highest.

## What is the efficiency of DC motor?

The value of the efficiency of a DC motor could typically be in the range of **70 to 85%**. Larger the machine higher will be the efficiency. Losses consist of Armature and field copper losses, core loss, friction and windage loss.

## What is the no load speed?

]The no load speed is **the RPM at which the DC Motor’s shaft rotate when there is no load attached to it** (no torque applied to the output shaft). It is the maximum output speed of the motor.
