Omron R88D-KN02H-ECT 200w Servo drive + Omron R88M-K20030T-S2 Servo motor + Robostar linear actuator positioning table RS-120-Y20PR ST 450 (120 mm with) + electronic positioning limiters.

This is an ultra-strong positioning table that weighs more than 30 lbs by itself.

Cheap CNC systems use stepper motors. Expensive robotics and industrial machines use Servo Motors, which have far higher accuracy (stepper motors use on average 200 electrical impulses per full rotation, while servo motors can have up to one million), more power, a far higher consistency under variable load condition, and precise feedback loops relating to position. (see detailed difference outlined below).

Here's your chance to get refurbished Servo motors and drives from Omron, the Rolls Royce brand of electronics, at a little over 10% of the new cost, for the cost of a stepper motor basically. We have 20 sets available.

Servo motors

Control: Closed-loop system that uses a feedback sensor (like an encoder) to continuously monitor and adjust position, speed, and torque.

Accuracy: High accuracy and repeatability, especially in dynamic environments or under varying loads.

Speed and Torque: Generally faster and can maintain high torque at higher speeds; they also have better overload capability and heat resistance.

Complexity and Cost: More complex and expensive due to the feedback components and control electronics.

Best for: Robotics, precision machinery, and other dynamic applications where high accuracy, speed, and consistent performance under variable loads are crucial.

Stepper motors

Control: Open-loop system where the motor moves in a predetermined number of steps without a position sensor.
Accuracy: High accuracy at low speeds, but can lose steps and position if overloaded or at high speeds, leading to inaccuracies.
Speed and Torque: High holding torque at zero speed, but torque decreases as speed increases. They are prone to vibration at low frequencies.
Complexity and Cost: Simpler, less expensive, and easier to control.
