# Frequent question: What can we control on a DC motor?

Contents

## What can a DC motor be used for?

At home, small DC motors are used in tools, toys and various household appliances. In retail, the applications of DC motors include conveyors and turntables, while in an industrial setting, large DC motor uses also include braking and reversing applications.

## Can you control a DC motor?

Thus, the speed of a DC motor can be controlled in three ways: By varying the supply voltage. By varying the flux, and by varying the current through the field winding. By varying the armature voltage, and by varying the armature resistance.

## What are the types of control for DC motor?

There are three main ways to achieve speed regulation in series DC motors–flux control, voltage control, and armature resistance control. In the flux control method, a rheostat (a type of variable resistor) is connected in series with the field windings.

## Why do we need to control DC motors?

Without control of the DC motor torque/current, the motor is allowed to pull large currents that can often result in torques delivered in excess of what is mechanically viable for the system, leading to imminent failure (especially when gear with a large reduction ratio is used).

## What is DC motor controller?

A DC motor controller manipulates the position, speed, or torque of a DC-powered motor and easily reverses, so the DC current runs in the opposite direction. Enjoy higher starting torque, quick starting and stopping, reversing, variable speeds with voltage input and more.

## How do DC motors work physics?

Electric motors use the forces produced by magnetic fields to produce a turning motion. If you put a length of wire in a magnetic field and pass a DC current through it (such as from a battery), the wire will move. This is called the motor effect .

## How does a motor control work?

Motor controllers are usually supplied with AC power. The power that comes in to a controller is at a set frequency. The motor controller first turns that AC to DC, then turns the DC back into AC at the right frequency. It uses a device called a rectifier to make DC current.

## Can motor control?

The Motor Controller 5 A CAN is a microcontroller based module for automotive and other applications. User configuration and programming facilitate implementation of a wide range of applications. The very compact form factor supports versatile use.

## Why are motor controllers needed?

A Motor Controller is a device that acts as intermediary between your robot’s microcontroller, batteries and motors. A motor controller is necessary because a microcontroller can usually only provide roughly 0.1 Amps of current whereas most actuators (DC motors, DC gear motors, servo motors etc.) require several Amps.
