Parker Hannifin launches new PSD servo drive software with torque, force control and advanced multi-axis functions.

The most common arrangement, which is used with only minor variations from small drives of say 0.5 kW up to the largest industrial drives of several megawatts, is the so-called two-loop control. This ...

In a speed controller, the motor’s speed (or velocity) is being controlled. There is an element that detects speed, whether it be a tachometer or some sort of encoder. This monitoring element provides ...

Engineers who work in motion control often start out using a relatively simple approach involving stepper motors to synthesize moves. Steppers are appealing in that their controllers can be simple and ...

Distributing power between all four wheels makes it easier to keep driving through tough conditions, or simply have more confidence for whatever might come up the road. However, some all-wheel drive ...

Just when it seems like the internal combustion engine has reached a performance peak, another automaker pushes the power and torque bar even higher. Thanks to sophisticated computerized sensing and ...
