Rochester, NY: Teknic recently launched Spring Applied, Power-Off Motor Brakes. Ideal for OEM manufactures looking for a simple method to hold or stop an axis (such as vertical axes) when power is removed. Available online with a fast 3-day lead time. NEMA 23 and 34 frame sizing available, starting at $219 in single piece pricing.
Key Features and Benefits at a Glance
- Spring applied, power-off: Teknic motor brakes will hold/stop the load when power is removed or lost. This fail-safe mechanism will prevent axes from moving (or stop axes already in motion).
- Front-mounted: Brakes have NEMA-standard input/output mounting flanges. The front mount is compatible with Teknic’s integrated servos (ClearPath), standalone brushless servo motors (Hudson), and stepper motors with or without encoders.
- Fast Lead time: The first 5 units ship in 3 business days; the remainder will ship within 3 weeks.
- Performance: Zero backlash, low inertia (will not degrade motor performance)
- Power: Low current draw (less than 500 milliamps)
- Test with Confidence: 90-day money back guarantee; 3-year warranty
- Shaft sizes: NEMA 23 shaft diameter: 3/8″; NEMA 34 shaft diameter: 1/2″
