Brushless DC Servo Motors
- Uncompromised High Power & Speed Output
BLDC motors maintain high torque and power efficiency across their entire speed range—enabling faster move times, higher throughput, and reliable motion under heavy loads. - High Precision & 360° Absolute Positioning
High-resolution encoder ensures exceptional positioning accuracy and repeatability. Single-turn absolute encoder sets position and phase reference instantly on startup — enabling maximum performance on startup. - Silent, Smooth, and Cool Operation
Optimized for Zaber's controllers and advanced features such as closed loop position control and field oriented control. Low internal thermal dissipation keeps motor temperatures low, preserving sensitive thermal conditions in optical or life sciences applications. - Direct Torque Sensing
Real-time motor current monitoring enables direct torque sensing, force-limiting, and collision detection — enabling active force control without the cost or integration of external load cells.
Why Choose Brushless DC?
Brushless DC (BLDC) motors and servo screw-drive stages bridge the gap between traditional steppers and direct-drive systems. These deliver the high thrust of a screw-drive with the quiet, high-throughput performance of a servo motor.
- Silent, smooth and cool operation
- Higher power output
- Faster move times without stepper torque drop-off
- Real-time motor current monitoring provides torque/thrust measurement
- True closed-loop servo control — no missed steps or stalls
Applications
- BLDC motors and linear stages or actuators are ideal for demanding operations where precision, force control, and quiet performance are essential:
- Semiconductor & Electronics: Rapid "step-and-settle" times for high-throughput wafer inspection and electronics assembly. Enables delicate component probing, pressing, and micro-assembly without external sensors.
- Microscopy & Life Sciences: Optical alignment, live-cell imaging, and clinical automation sensitive to heat expansion or noise. Ideal for automated syringe or pipette pressing where precise contact detection and force-limiting are required.
- Industrial Photonics & Optics: Heavy payload capacity and smooth power delivery provide stable motion under dynamic loads. High torque across high RPM ranges makes it ideal for continuous-duty applications like laser marking, cutting, machining, and material processing.
