What size are pancake motors?

Introduction: What are Pancake Motors?

Pancake motors are a type of electric motor that have a disc-like shape, with a diameter generally exceeding their height. They are known for their high power density, outstanding efficiency, and ultra-fast speed. Due to these characteristics, they have found applications in various industries such as medical equipment, wearable device, robotics, and automotive.

Sizes of Pancake Motors

1. Coin Pancake Motors

Coin pancake motors are as thin as a coin. They are typically used in small and portable devices such as smartphones, e-cigarrete and earbuds. The diameter of these motors ranges from 8mm to 12mm. Coin pancake motors have a limited service life due to their small size, but they can operate silently and have a high acceleration rate.

2. Linear Pancake Motors

Linear pancake motors use the same technology as the rotary pancake motor, but their disc has been unrolled into a flat coil. The diameter of these motor is 8mm with 2.5mm and 3.2mm thickness. They offer a compact and low profile design, making them an excellent choice for various applications. It is widely used on electronics products that require haptic feedbacks such as high-end smartwatches.

3. Brushless Pancake Motors

Brushless pancake motors, also known as flat motors or disc motors. They do not use brushes to transfer power. Instead, they use a brushless DC motor (BLDC) system, which gives them better performance, more efficiency, and a longer lifespan. Brushless motors are the smallest type of pancake motors. The diameter of these motors ranges from 6mm to 12mm. They mainly used on high-end wearable devices, beauty appratus and medical devices.

Conclusion: Choosing the Right Pancake Motor

Choosing the right pancake motor size and type is crucial to ensuring the optimal performance of your application. Regardless of the size or type you choose, pancake motors provide many benefits such as high efficiency, compact design, and high power density.
