Most hybrid motors step fast like variable reluctance varieties, while boosting torque with permanent magnets. But these stepmotors go one step further
Most hybrid motors step fast like variable reluctance varieties, while boosting torque with permanent magnets. But these stepmotors go one step further using precision stators to maximize torque density by minimizing the airgap. The stators are bored out with a honing mandrel, resulting in an extra-tight fit between rotor and stator. A motor with a 1.30-in. stack can now produce 2.5 oz-in. of torque combined with the accuracy of two-phase 1.8° stepping.
What it means to you: The smallest NEMA-8 two-phase hybrid stepper available, generating 2.5 oz-in. of holding torque from a 1.30-in. stack with a 0.79-in. square cross-section
What else: A larger version (1.69 in.) weighing only 0.13-lb produces 4.2 oz-in. of torque; rear-shaft extension standard on all models.
