There's a common belief that two servos with the same power range from different manufacturers are roughly equivalent, and that the only other significant comparison point is price. This just isn't true, and the information provided below will debunk that belief. There are several important features you cannot afford to ignore when comparing servo motors, including:
What else can a servo motor do?
In Servo Motors: An In-Depth Introduction, Part 1, we reviewed how servo motor construction and operating characteristics create this technology's advantages. But there's more to understanding how servo motors can play an important role in automation solutions. Shaft sensors and holding brakes provide 4 different kinds of feedback and can extend the life of the equipment for maximum efficiency.
What is a servo motor, and what are they used for?
A servo drive system breaks down into two main components: the servo motor and a servo drive. The servo drive converts electrical power from the connected line supply in a controlled manner into power for the motor. The servo drive consists of power electronics and control electronics for regulation, set point generation, and component monitoring.
The servo motor converts the electrical power into movement. It consists of torque generating components, the sensor for angle and feedback and, in some cases, a holding brake to maintain position at zero current. Generally, the operation of servo motors is characterized by frequent changes in speed and torque, operation at standstill to hold positions, and short-term operation with high overloads.
To understand the advantages of a servo motor, let's consider the inner workings: construction, operating characteristics, sensors, and brakes.
Does every inch count in your control cabinet? Then look no further than Siemens Sirius 3RM1 hybrid motor starter. This motor starter can reduce space requirements in the control cabinet by up to 82 percent, while still providing integrated overload protection for smaller motors. The SIRIUS 3RM1 combines the functionality of contractors and overload relays in a width of just 22.5mm.
For many industrial companies, energy is one of the biggest expenses they have to burden, and even though control panels are a vital component to any process plant, their potential to offer energy savings is often overlooked. Energy efficient motors use less electricity, run cooler, and often last longer than NEMA (National Electrical Manufacturers Association) B motors of the same size. Here are some of the top advantages of energy efficient control panels.
Compact Hybrid Motor Starters combine relay and semi-conductor technology with integrated electronic overload protection and safe shut down functionality with a width of only 22.5 mm for motors up to 3 horse power.
