The difference between brushed and brushless servo motors is the mechanism used for commutation. Servo motors move or create torque based on magnetic forces being in opposition. In the simplest… Read more »
The final topic in this chapter is the use fo a rotary axis. A rotary axis is most often found in the form of a rotary table or an indexing… Read more »
In older brushed servo motors, the phasing of the current supplied to the rotor was determined by the orientation of the commutator, a plate on the rotor which interated with… Read more »
The servosystem is one in which the output is some mechanical variable like position, velocity or acceleration. Such systems are generally automatic controls system which work on the error signals…. Read more »
There are four basic types of gear reducers on the market today:helical gears,parellel shaft helical gears,helical bevel gears,and helical worm gears. The latter three types of gear reducers are often… Read more »
Linear actuators are utilized inside a number of applications like healthcare gear, test instruments, factory processes and assembly machinery. Because every application may have its personal overall performance and security… Read more »
What is a Gearmotor? A small motor (ac induction, permanent magnet dc, or brushless dc) designed specifically with an integral (not separable) gear reducer (gearhead). The end shield on the… Read more »
There are serveral types of stepper motor currently availbale, with permanent magnet or soft iron rotors, and there are hybrids. Permanent magnet stepper motors have found the widest application because… Read more »
If variable loads are exerted upon a motor-driven piece of equipment, a variable frequency drive (VFD) or Variable speed drive (VSD) can make a significant difference in the amount of… Read more »
Pumping systems account for nearly 20% of the world’s energy used by electric motors and 25% to 50% of the total electrical energy usage in certain industrial facilities. Significant opportunities… Read more »
