DC Motors
Direct current (DC) motors are electric machine types designed to transform electrical energy (DC) into mechanical rotation (mechanical energy). These motors are widely used in various applications, ranging from small tools and toys to electric automobiles, compared to AC systems. A DC motor uses a magnetic field resulting from electric currents. The resultant magnetic field triggers the built-in rotors to rotate in the output shaft, where the speed and torque mainly rely on the motor designs and electric inputs. They also allow for controlling speed across distinct supply voltages where the most familiar voltages include 12 and 24 v. Additionally, they are available in varied types suitable for a great range of applications in various settings and devices.
Key Advantages of DC Motors:
Direct current motors provide a plethora of benefits, such as:
- They are easy to install and lightweight.
- Cost-effective and allows highly efficient performance.
- Provide speed control across distinct voltages.
- Features remarkable reversing and acceleration with quick star and off options.
- Provide linear speed torque curve.
- Ideal for various applications.
- Extremely durable with long-lasting service life.
How Many Types of DC Motors Are There?
The DC motors are categorised into two types, including:
- Brushed Motors - Brushed motors are the most widely used conventional motor type, with huge contributions to consumer and industrial applications. They are preferred motors for cost-sensitive uses with simple control systems.
- Brushless Motors - Brushless motors are devoid of brushes, with simple designs and long-life spans. They are highly efficient and provide up to 85–90% efficiency with minimal maintenance requirements. They are used in highly demanding applications for speed and positional control where ruggedness and reliability are indispensable. Fans, air compressors, and pumps are examples of suitable applications.
What Are DC Geared Motors?
DC gear motors feature a motor and a gearbox for generating single motion control components; however, they have a basic DC motor design. The built-in additional gear head enhances the torque output while minimising the speed.
DC Motor Applications:
DC motors have a vast range of domestic, commercial, and industrial applications. They are used for various appliances with specific functionalities and include:
- DC motor for blowers and fans
- DC motor for pumps (centrifugal and reciprocating)
- Drilling machines
- DC motor for toys
- Milling machines
- DC motor for robots
- Machine tools
- Conveyors
- Elevators, Hoists
- Cranes
- Electric Vehicles
- DC motor for bikes.

LT2020A-050K05, PiezoMotor
Piezo LEGS® Linear Twin 20N LT20 Series
The LT20 is a compact yet strong linear motor for build-in original equipment manufacturer (OEM) applications characterised by its outstanding precision. It features predictable submicron, direct-drive motion without backlash with resolution down to single nanometre level or below.
Lack of gear-heads and linear screws reduces the overall size so that the LT20 often fits where other motors will not. In place, it delivers up to 20 Ns force and its friction drive ensures full-force, power-off locking with no mechanical play or backlash.
The motor can be integrated easily into an application using the drive rod mechanical adapter. The LT20 motor is also capable of moving in full steps (waveform) or partial (microsteps).
Any 'move-and hold' application that requires high precision, instant response and low power consumption benefits from LT20s Piezo LEGS® technology.
