Frequently Asked Questions (FAQ)
Q: What is the primary benefit of choosing this 90mm hybrid stepper motor?
A: The main benefit is the motor’s highly reliable positioning and maximum static holding torque. This 90mm hybrid stepper motor is a proven solution for large-scale industrial tasks that demand high positional repeatability.
Q: Why is the 90HSD Series not listed under a standard NEMA size?
A: The 90HSD Series utilizes a 90×90 mm frame, which is an exclusive AKT standard. This size is optimized to provide maximum torque density for heavy-duty applications, rather than fitting a smaller standard NEMA frame like NEMA 34 (86mm).
Q: Should I choose this stepper motor or a high-power BLDC motor for my application?
A: The choice depends on the required operational speed. Stepper motors are ideal for high-torque positioning and holding a fixed position. A high-power BLDC motor would be a better choice for continuous, high-speed operation where energy efficiency and lower noise are critical.
Q: What is the step angle accuracy of the 90HSD Series?
A: The 90HSD Series provides the standard 1.8° step angle. Utilizing micro-stepping technology is the best way to achieve finer resolution and smoother operation with this industrial-grade stepper motor.
