Latest Patents

One of Richard's latest patents is for an 8-pole, 2-phase bipolar step motor designed for easy manufacture and optimum torque for size. This innovative step motor features a uniform 8-stator pole design, which maintains a close ratio between the number of stator teeth and rotor teeth to improve torque. The design specifies that if D is the nominal inner diameter of the stator in millimeters, the number of stator teeth per pole should equal D divided by 3, rounded to the nearest integer. This configuration accommodates the necessary winding needle space between adjacent stator poles. Additionally, the step motor includes a rotor mounted for rotation within the stator, featuring a plurality of rotor teeth. The respective numbers of rotor and stator teeth may differ by at most two or maintain a tooth ratio greater than 95%. The design also emphasizes the importance of minimum tooth width and separation of at least 0.5 mm for effective magnetic interaction.

Another significant patent involves a step motor that integrates its mounting face and heat sink into the stator design. This innovative approach allows the stator stack to serve as the mounting surface, facilitating direct heat conduction from the stator to the mounting plate. The design includes mounting holes through the stator stack, ensuring efficient heat dissipation. The rotor is held in alignment by an end cap situated inside the stator's mounting surface, which does not contribute to the mounting process but ensures proper rotor positioning.
