NovoSphere Nema 34 Closed Loop Stepper Kit vs Eugene Color Nema34 Closed Loop Stepper Kit

Both are Nema 34 closed-loop stepper kits with 1.8° step angle and 6A phase current, but they are not equals. The Eugene Color kit delivers 12.2 Nm holding torque versus 8.5 Nm on the NovoSphere, and its HBS86H driver accepts a wide 30-100V DC supply. The NovoSphere adds a brake, which holds a vertical load when power is cut, and it ships with a 1.5 m encoder cable. Owners of high-torque Nema 34 builds generally report the larger Eugene Color motor runs cooler and holds position better under load; the NovoSphere brake is the deciding feature for Z-axis and lift applications.

• Choose the NovoSphere if you need a motor brake to hold a vertical axis or load when power drops, and 8.5 Nm is enough for your machine.
• Choose the Eugene Color if you want maximum holding torque and a driver that runs on a wide 30-100V supply, and you do not need a brake.
