Definition
The speed of the motor is the rotational speed of the motor shaft. In motion applications, the speed of the motor determines how fast the shaft rotates—the number of complete revolutions per unit time. Application speed requirements vary, depending on what is being moved and coordination with other components of the machine. A balance must be achieved between speed and torque because motors typically produce less torque when running at high speeds.
Solution overview
We meet speed requirements during the design process by creating optimal coil (often called winding) and magnet configurations. In some designs, the coil rotates according to the motor structure. Creating a motor design that eliminates the binding of iron to the coil allows for higher speeds. The inertia of these high-speed motors is significantly reduced while also increasing acceleration (responsiveness). In some designs, the magnet rotates with the shaft. Since magnets are a contributor to motor inertia, a different design than standard cylindrical magnets needed to be developed. Reducing inertia increases speed and acceleration.
TT MOTOR TECHNOLOGY CO., LTD.
TT MOTOR designs high-speed motors with self-supporting high-density rotor coils for our brushless DC and brushed DC technologies. The ironless nature of brushed DC coils allows for high acceleration and higher speeds, especially compared to brushed DC motors with iron core designs.
TT MOTOR high speed motors are ideally suited for the following applications:
Respiratory and ventilatory equipment
Laboratory automation
Micropump
Electric hand tools
Yarn guide
Bar code scanner
