Q: What is the difference between Unipolar and Bipolar motors?
A: A traditional unipolar wound motor has six lead wires. Each winding has a center tap. Unipolar wound motors are typically used in applications requiring high speed and high torque. A traditional bipolar wound motor has four lead wires. There is no center tap in each winding. Bipolar wound motors are typically used in applications required high torque at low speeds.
Q: My stepper motor is running hot to the touch. Is there something wrong?
A: Stepper motors are designed to run hot. Our Hybrid stepper motors are rated to run in an ambient temperature range of 20 degrees C to 50 degrees C and can have a temperature rise of 80 degrees C. It is common for stepper motors to run hot because they are often driven at a constant current.
