Made of high quality cold roll sheet copper and anti-high temperature permanent magnet, Leadshine’s stepper motors are highly reliable and generate low motor heating. Because of their nice internal damping characteristics, those stepping motors can run very smoothly and have no obvious resonance area within the whole speed ranges.The 86HS45 two-phase stepper motor is suitable for a wide range of motion control applications. Terminated with 8 motor leads, the motor can be connected in a few different ways, including bipolar series, bipolar parallel and unipolar.
1. 2 phase 1.8 degree stepping angle.
2. NEMA 34.
3. Holding toque of 4.5 N*m (637 oz-in).
4. High precision.
5. Smooth movement.
6. Low motor heating.
7. Low movement noise.

Unipolar and bipolar half coil, because we are using less turns, does not give us great low speed torque, but because of the low inductance, holds the torque out to high speeds. Bipolar series uses the full coil so it gives very good low speed torque. But because of the high inductance, the torque drops off rapidly. Bipolar parallel also uses the full coil so it gives good low speed performance. And its low inductance allows the torque to be held out to high speeds. But remember, we must increase current by 40% to get those advantages. Speed-torque curves show the maximum torques that can be output at a given speed. When selecting a motor, make sure the required torque falls within the particular curve.
