Omron R88M-1M1K020C-BS2 – 1S Series AC Servo Motor, 1 kW, 400 V, 2000 rpm, with Brake
The Omron R88M-1M1K020C-BS2 is an AC servo motor from Omron’s 1S series, rated 1 kW at 2000 rpm for 400 V servo drives. It delivers a rated torque of 4.77 Nm and a peak torque of 14.3 Nm. It has a battery-free absolute encoder, a holding brake, an oil seal and a 22 mm shaft with key and tap.
The 1S series is Omron’s compact servo platform for NJ/NX machine controllers over EtherCAT. The battery-free absolute multi-turn encoder keeps the axis position after power-off without batteries to replace, which means no homing on start-up and less maintenance. The integrated holding brake keeps the axis in position when the drive is off, which is essential for vertical axes and loads that must not move. The 2000 rpm, 130 mm flange design gives high torque for heavier loads.
