Product Description:
The S34GNNA-HGNE-00 is a servo motor from Pacific Scientific that is made for automation tasks that need fine control. It is part of the SENTRY line and has a 6-pole Neodymium magnet structure. The frame is made of NEMA 34 steel, and the stack length is 3 inches. The product can be used in robots, clamping, coil winding, and packaging systems.
The S34GNNA-HGNE-00 servo motor has a Tcs rating of 58 and a Ke rating of 200. It can put out 6.5 lb-in of torque and has a constant stall current of 3.8 A. The back EMF is always 1.9 V/KRPM, and the resistance at the terminals is 7.2 ohms. The motor has a type G winding. The feedback system is made up of two parts. A Hall sensor is used for the main feedback, and a 1024 PPR incremental encoder with a line driver is used for the secondary feedback. The encoder gives off a quadrature signal on two channels and an index pulse. It has complementary signals and a 26LS31 TTL differential line driver that works with RS422A devices. The driver can handle frequencies up to 100 kHz and is safe against short circuits. The feedback design makes it possible to integrate industrial automation.
The S34GNNA-HGNE-00 has a secondary feedback encoder that works with RS422A standard signal levels to make it less sensitive to noise. The encoder needs a power source of +5 VDC ±10% and a current of 165 mA. The motor is made without a holding stop and without a shaft seal. The design allows for easy installation in a range of machine setups. It works well for wrapping lines that need to keep things in the same place and control the speed.
Frequently Asked Questions about S34GNNA-HGNE-00:
Q: Why does S34GNNA-HGNE-00 have a 6-pole Neodymium structure?
A: The 6-pole Neodymium configuration provides higher torque density and compact form factor. It increases the magnetic strength, which improves control precision in a limited space.
Q: Why does S34GNNA-HGNE-00 feature a 1024 PPR encoder?
A: The 1024 pulses per revolution encoder ensures accurate position and speed feedback. It enhances precision in tasks like X-Y table control and fluid metering.
Q: Does S34GNNA-HGNE-00 use differential line drivers?
A: Yes, it uses 26LS31 TTL differential drivers based on RS422A. These provide noise-immune signal transmission over longer cable lengths for better signal integrity.
Q: Why is S34GNNA-HGNE-00 rated at 3.8 A continuous stall?
A: The 3.8 A stall current ensures steady torque without overheating. It is designed for sustained loads during low-speed, high-torque operations like clamping and gauging.
Q: How does S34GNNA-HGNE-00 handle encoder signal accuracy?
A: It includes an index pulse and dual-channel quadrature output. These features enable accurate shaft positioning and direction sensing for coordinated motion systems.
