Product Description

The SF-A2.0020.060-04.050 by Rexroth Indramat is manufactured to be used with a digital Servodyn-D (closed loop) system. Brushless motors are a relatively new invention, and they are widely used in applications that require high performance. These motors employ electronic transmission to regulate the magnetic fields instead of brushes. The SF and SR motors are differentiated based on the integrated encoder. STG or MTG encoders are found in the motors that are part of the SF series. The SF series consists of very small, permanently energized synchronous motors optimized to run at a direct current linkage voltage of 670 V.

A sinusoidal EMF is a potential difference or electrical voltage that fluctuates sinusoidally over time. This indicates that the voltage oscillates between values that are positive and negative in a sine wave pattern. The motor's lifespan is extended by the smooth sinusoidal current, which can tolerate heat and mechanical load. Permanent magnets included in brushless motors cause the system's rotors and stators to rotate at the same speed. The locked torque of the rotor is produced by the servo motor when it is in the zero speed or rest position.

The horsepower and particular design of the motor determine the magnitude of the rotor's locked current. The speed at which the rotor rotates because of the magnetic field is 6,000 per minute. The holding brake in the 050 version servo motor follows the fail-safe principle to stop the rotation of the rotating shaft when the motor is de-energized. Investing in brushless servo motors is worthwhile if you want great efficiency, accurate control, and long-term dependability for applications that require high performance.
