Heat and noise both depend on the type of stepper motor, the conditions in which it operates, and what functions the motor serves in the application. Permanent-magnet stepper motors are usually most quiet, as they have a smooth rotor. Hybrid stepper motors are quiet as well. In contrast, variable-reluctance stepper motors are the noisiest type […]
FAQ: What is pole count and why does it matter?
Simply defined, a pole is a north or south magnetic field of force that is generated by a permanent magnet or current passing through a coil of wire. For stepper motors, however, this definition does not necessarily translate to a simple definition of pole count. Different manufacturers use different names to refer to their poles […]
Spectral Decomposition for fast servo control from Delta Tau
Delta Tau now offers a new control method called Spectral Decomposition to improve the productivity of systems that use fast-tool actuators. Spectral Decomposition works with a variety of fast-tool actuators—including voice-coil motors, piezo crystals, laser galvanometers and magnetostrictive transducers. These actuators have high bandwidth, but limited travel. So they are typically paired with a standard […]
New brushless DC motor and gearhead by maxon with high rpm, power and both are sterilizable
The new brushless BLDC motor EC 19 has been specially designed for high speeds and features low heat development and extremely quiet and low-vibration running. It has applications in centers for miniaturized processing, hand-held tools and medical technology. When combined with planetary gearhead GP 19 M, many possible variations are available for applications in these […]
maxon’s new high power motor can withstand high temperatures, pressures and deep depths
The new, electronically commutated EC-4pole 32 HD with planetary gearhead motor by maxon precision motors has all the features of its predecessor, the Heavy Duty Motor EC 22 HD, but with a larger and more powerful size. It is designed for extremely rough operating conditions, particularly applications in deep drilling. Deep drilling technology makes it […]
