The Importance of Heat Management in Electric Motors

Effective dissipation of heat generated during the operation of electric machines is a critical challenge for design engineers. Heat limits the amount of torque a motor can produce. Increasing electrical current to boost torque also increases heat generation. Efficient cooling is essential to maximize the motor's current rating and delivered torque.

Coolslot™ vs. Traditional Cooling Methods

Coolslot™ offers a significant advancement over traditional cooling methods, particularly external water jacket cooling. By adopting an in-slot cooling approach, Coolslot™ ensures better thermal connectivity between the cooling fluid and the stator windings. This proximity enables more effective cooling, resulting in higher current capacity and increased torque output.

Benefits of Coolslot™ Design

The primary benefit of the Coolslot™ design is its superior torque density. Coolslot™-enabled motors can deliver more torque within the same size envelope or achieve the same torque output with approximately 50% reduced size and weight compared to traditional designs. Additionally, Coolslot™ technology offers cost savings due to lower material usage and enhanced efficiency by operating at lower steady-state temperatures.

Coolslot™ Overcoming Challenges and Electromagnetic Considerations

Coolslot™ has successfully addressed key challenges associated with in-slot cooling, including manufacturability, reliability, and electromagnetic performance. Unlike nonconductive coolant and tubing approaches, Coolslot™ employs conductive fluid (such as water) and tubing (copper or stainless-steel) for optimal thermal properties. The unique patented design mitigates negative electromagnetic effects, allowing for efficient operation at lower frequencies. However, higher frequencies may impose performance limitations, and smaller larger motors tend to benefit more from the reduced size and cost advantages offered by Coolslot™ technology.
