Highest Torque Density AC Servo Actuator

The new SHA brushless servo-actuator from Harmonic Drive LLC provides the highest torque density of any actuator in its class

The new SHA brushless servo-actuator from Harmonic Drive LLC provides the highest torque density of any actuator in its class. Positional accuracy better than 1 arc-min and ±5 arc-sec repeatability is achieved while delivering up to 30,000 in-lb of torque. A robust cross-roller bearing allows mounting of large loads directly to the actuator without additional support. The SHA Series actuator also features a compact, hollow shaft configuration that allows design versatility for demanding applications. Features include:

• Hollow-shaft: Inside diameter up to φ65mm
• Flat Design: Actuator length is shorter than its outside diameter
• Torque to Volume Ratio: More than 5 times that of a Direct Drive Motor
• Output Torque: up to 3400 Nm
• Output bearing, gear reduction and motor winding specification to suit your needs.
• 17bit Magnetic Absolute Encoder
• It is also available to order as a "motor only"
• Now available with hollow shaft planetary gear option - HPF series HarmonicPlanetary® - for higher output speeds
• New option - low voltage winding, 48V DC to 90V DC available for same sizes

Zaber's Fastest, Longest Travel Stage

Zaber's Fastest, Longest Travel Stage

Zaber's new and improved stage (X-BLQ-E) is a closed-loop, belt-driven motorized linear stage with built-in motor encoder and controller. With travel lengths up to 3 m, 10 µm repeatability, and a maximum speed of 2.0 m/s, X-BLQ-E stages are perfect for rapid positioning over large distances. A built-in motor encoder allows closed-loop operation and slip/stall recovery, and an optional indexed knob provides manual control for operation without a computer. Like all Zaber products, the X-BLQ-E Series is designed for easy set-up and operation.
