Tubular Linear Motor Magnets

Tubular Linear Motor Magnets About Tubular Linear Motor Magnets Halbach array in tubular linear motor is made of radially oriented magnets and axial magnetized magnets which arranged in a certain order, then obtain much stronger sinusoidal distributed magnetic field on the working side and keeping the field to a very low value on the other [...]

What is a torque motor?

What is a torque motor? Rotational electric motors have been around for ages but a lot has changed since then. How did electric motors change? What innovations have been made? Torque motors have benefitted greatly from the knowledge gained making linear motors. Utilizing a brushless 3-phase design they can provide even greater efficiency and power, [...]

How linear motors work

How linear motors work? In a traditional DC electric motor, a central core of tightly wrapped magnetic material (known as the rotor) spins at high speed between the fixed poles of a magnet (known as the stator) when an electric current is applied. In an AC induction motor, electromagnets positioned around the edge of the [...]

Linear Motors – The Future!

Linear Motors - The Future!!! The future is linear motor! In high-speed pick and place machines speed is everything. With speed comes friction, with friction comes maintanence, with maintanance comes downtime, with downtime comes lost productivity. By removing the components needed to transfer rotary to linear motion, the system becomes much lighter and more efficient. [...]

What is a linear motor – Direct drive advantages

Why adopt linear motors? Direct coupling of the payload to the motor’s moving part eliminates the need for mechanical transmission elements such as leadscrews, timing belts, rack and pinion, and worm gear drives. Unlike brushed motors, there is no contact between the moving parts in a direct drive system. Therefore there is no mechanical wear [...]

What is a linear motor – Principle

Linear motors are a special class of synchronous brushless servo motors. They work like torque motors, but are opened up and rolled out flat. Through the electromagnetic interaction between a coil assembly (primary part) and a permanent magnet assembly (secondary part), the electrical energy is converted to linear mechanical energy with a high level of [...]
