AC Servo Motor 1000W ECM-B3M-C21010RS1 (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, offer a major technological leap forward, which will result in more advanced systems, shorter cycle times and possibly the associated cost savings.

Also in the area of encoder resolutions, major steps forward have been made. Various 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 multi-turn (17-bit). Compared to the previous ECMA motors that were 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 a 24-bit incremental optical encoder, which can be used as an absolute encoder within the range of 1 revolution.

Despite the increased performance, the new ECM-B3 AC servo motors are more compact than the previous generations of Delta AC servo motors, such as the ECMA motors. For a 1000W servo motor with a flange size of 100x100mm, the length has been reduced by approximately 3%. The flange sizes and shaft diameters have remained the same, which makes switching from ECMA motors to the new ECM-B3 motors possible without any problems.

Component features:
