AC Servo Motor 200W ECM-B3M-C20602RS1 (24-bit INC encoder)

The ECM-B3 AC servo motors are suitable for the Delta B3 and Delta B3A Delta servo drivers. These motors, in combination with the B3 drivers, provide a major technological leap forward, which result in more advanced systems, shorter cycle times and potentially associated cost savings.

The performance of the motors has actually increased. The maximum speed is increased from 5000 RPM to 6000 RPM. The short-term torque increase of 300% has now also been increased to 350%. This means systems can accelerate and decelerate more quickly, to further reduce cycle times.

Major steps forward have also been made in the field of encoder resolution. Different types of encoder are available: in addition to the 17-bit incremental magnetic encoder, there is now also a 24-bit incremental optical encoder and even a 24-bit absolute optical encoder, which also works in mult-turn (17-bit). Compared to the previous ECMA motors suitable for the B2 system, this 24-bit encoder is a giant leap from 160,000 pulses/rev to 16,777,216 pulses per revolution. The servo motor offered here also has an 24 bit magnetic incremental encoder, within the range of 1 turn, it can be used as a single turn absolute encoder.

Despite the increased performance, the new ECM-B3 AC servo motors are much more compact than previous generations of Delta AC servo motors, such as the ECMA motors. For a 200W servo motor with a flange size of 60x60mm, the length has been reduced by approximately 31%. The flange sizes and shaft diameters have remained the same, which makes switching from ECMA motors to ECM-B3 motors possible without any problems.
