# What kind of load is a motor?

## Is a motor a resistive load?

As you might guess from the name, resistive loads only resist the current and are the simplest type of load. In inductive loads, such as an electric motor, the voltage wave is ahead of the current wave.

## Is a motor a load or source?

In a more general sense, any resistor or electric motor in a circuit that converts electrical energy into light, heat, or useful motion constitutes a load on the circuit.

## What is the load on an electric motor?

Electric motor load means the current drawn by an electric motor. It depends upon the load on the shaft of the motor. For a given electric motor, it can estimated using input power, amperage or speed of the motor.

## What type of load is DC motor?

DC motor is both inductive and resitive load. 2.as the current flowing in the armature is ac with some frequency it produces an inductance property in the armature winding.

## Is a motor inductive or capacitive?

Reactive/Inductive Load – An inductive load converts current into a magnetic field. Inductive reactance resists the change to current, causing the circuit current to lag voltage. Examples of devices producing reactive/inductive loads include motors, transformers and chokes.

## Is the load inductive or capacitive?

Capacitive load is similar to that of inductive load. In capacitive loads also, current & voltage are out of phase with each other. The only difference is that, in capacitive load current leads the voltage by 90 deg. Whereas, in inductive load current lags behind the voltage by 90 deg.

## What is motor and its types?

We know there are generally two types of motors, AC motor, and DC motor. AC motors are flexible for speed control and demand low power during start. On the other hand, DC motors are widely used due to its initial cost of low power units is less compared to AC and can be easily installed.

## What is a commutator in a motor?

A commutator is a rotary electrical switch that periodically reverses the current between the rotor and the external circuit. The commutator was discovered by William Ritchie and Hippolyte Pixii in 1832. Commutators are used in DC machines (DC motors and DC generators) universal motors.

## Is a switch a load?

A load switch is simply a switch, mechanical or electronic, that connects or disconnects a load to the high side of a power source. A wall light switch is a load switch. Any off/on switch on an appliance or electronic product is a load switch. A relay can be a load switch.

## What is a motor under load?

Underload motor protection compares the value of the phase current minimum I MIN with the setting value of the protection Iund pickup. If the current value I MIN falls below the Iund pickup, the protection tund time delay is actuated. By default, underload motor protection is not active.

## What is the unit of motor load?

It is combination from Amperage and Voltage value. Basic formula for Power is P (watt) =I(ampere) x V (volt). Power also measured in Horsepower (hp) unit. For common conversion from electrical Horsepower to Watt is 1hp = 746 watt.

## How do you find the load of a motor?

When calculating motor loads, you need to know how to convert a motor’s current rating (given in amps) to a VA rating. To do this, multiply the motor’s nameplate amperage by the supply voltage.
