RSB-E Series: High speed motorized rotation stages with built-in motor encoders and Auto Detect
Speeds up to 500 rpm
Continuous 360° rotation stage
50.8 mm aperture
Multiple motor configurations
Encoder position feedback with slip/stall detection and automatic recovery
Designed for use with an X-MCC Series stepper motor controller or any 2-phase stepper motor controller
With Auto Detect, the X-MCC controller configures its settings automatically for the connected peripheral
Zaber's RSB-E Series motorized rotation stages have a 120 mm table diameter and a 50.8 mm (2 inch) aperture. They also feature a compact footprint, low profile, and a load capability of up to 50 kg. With a maximum rotational speed of 500 rpm, these rotation stages are ideal for the rapid positioning of light loads. A built-in motor encoder allows for closed-loop operation and slip/stall recovery features.
There are two motor configurations available: up and down. Motor up configurations allow flush mounting of the device to a flat surface, and motor down configurations allow for full 360° movement of loads that extend past the edge of the stage top.
The stages are designed to connect directly to our X-MCC Series universal motor controllers, or they can be used with any 2-phase stepper motor controller through the panel mount DB15 connector. Set up is easy with Auto Detect. Once connected, the X-MCC controller will automatically detect and configure the RSB-E.

Specification Charts and Notes
Thrust or torque is a function of speed. The values given above are maximums. These values cannot both be achieved simultaneously (i.e. at maximum speed, the unit will not produce maximum thrust).
