HOFON MOTOR

A DC motor works because a conductor carrying current inside a magnetic field experiences a force, and that force acting at a distance from the shaft becomes torque. The rotor turns, the motion gen...

A DC motor is an electrical machine that converts direct current into continuous rotation. Its definition rests on three things working together: a magnetic field that is stationary with respect to...

The noise level of a planetary gear motor cannot be read off a datasheet as a single product property. It is the outcome of four things working together: how well the teeth share load, how much bac...

A planetary gear motor is a geared motor whose reduction stage uses a sun gear at the centre, two or more planet gears meshing around it, and a ring gear enclosing the set. The sun drives the plane...

A low-speed worm gear motor should be specified from the output torque backwards, not from the output speed forwards. The ratio needed is a consequence of the torque the mechanism demands, and the ...

A worm gear motor is a geared motor in which the reduction is produced by a worm — a shaft carrying a helical screw thread — driving a worm wheel whose teeth mesh with that thread. Because the worm...

Adding a Hall encoder to a DC gear motor buys exactly one thing, and it is worth being precise about it: the drive can see where the output shaft is and how fast it is turning without relying on a ...

A stepper motor works by energising its stator phases in a fixed sequence rather than applying a continuous rotating field. Each change in that sequence pulls the rotor into a new alignment, so the...

Stepper motor vs servo motor is decided by four things, and accuracy is only one of them. If the axis moves slowly, holds a position against a load, and can live with open-loop control, a stepper i...

A stepper motor is an electric motor designed to move in discrete increments rather than continuously. Each electrical pulse applied by its driver advances the rotor by a fixed angle — the step ang...

DC gear motor specifications have a fixed reading order, and reading them out of order is the most common reason a motor gets ordered twice. A gear motor datasheet contains two machines in one docu...

A DC gear motor is a DC motor with a gearbox built onto its output — one assembly rather than two parts, in which the motor provides the rotational speed and the gearbox converts most of that speed...
