The new motor class
To reach higher efficiencies in asynchronous motors, as an example, you need more or higher-quality materials, such as copper. This makes the motors much larger and also heavier!
As the demands on asynchronous motors increase, the cost difference from more expensive but significantly more efficient servo drives shrinks.
And this is exactly where we come in: The strictly encoderless synchronous servo motor without a fan reaches efficiencies of up to 96% and energy efficiency class IE5 as a result!
At the same time, it is lighter and smaller than an asynchronous motor and less expensive and more rugged than a standard synchronous servo motor.
You get a more compact design and benefit from lower energy requirements and a long service life.
Completely without an encoder
The position and speed are determined in combination with the SC6 and SI6 drive controllers.
Despite not having an encoder in the motor, the speed deviation is less than 1%, while the positioning accuracy is ±1°.
Since the encoder is omitted, this motor class is ideal for dynamic automation tasks in harsh production environments.
With only one cable
Here’s the major advantage of the Lean motor. By leaving out an encoder, it can be continuously controlled with just a standard power cable without additional shielding.
This means less installation and routing effort, smaller drag chains, smaller control cabinet feed-throughs and lower costs.
The rugged and inexpensive alternative
By eliminating the encoder, the Lean motor uses a single off-the-shelf power cable with no additional shielded wires. These are two factors that make it up to 30% cheaper than a comparable synchronous servo motor.
Since the encoder is left out, the STOBER Lean motor can withstand high oscillations and vibrations.
And the reduced wiring also makes commissioning so much easier!
