Brushless DC Motors

BRUSHLESS MOTOR (BLDC MOTOR)

Portescap BLDC Motor technology continues to push the curve of high performance in both slotted and slotless DC brushless motors. With exceptional torque and speed, higher efficiency and package sizes suited to meet your needs, brushless DC motors meet even the most stringent requirements. A brushless DC motor offers excellent speed and position control, long life, and high torque density. Slotless electric brushless DC motors use a cylindrical ironless coil made in the same winding technique as ironless DC motors, while the slotted DC brushless motors are built with stators consisting of the latest technology in lamination and windings. Both are electronically commutated and have 3 winding phases. Our slotted brushless DC motors are manufactured in the USA and targeted towards performance-critical surgical power devices and also offer sterilization capabilities.

We also offer an optimized line of brushless DC motors / miniature brushless motors, Ultra EC, designed in Switzerland. This family of small dc motors helps you address a wide range of specific requirements for torque and speed while providing decreased iron losses, improved efficiency and cooler operation.

Our DC brushless motors perform exceptionally well in environments requiring both precision and durability. The unique design of a BLDC motor allows for several key benefits:

Diameters as small as 12.7 mm
Speeds up to 100,000 rpm
High motion efficiency
Ability to withstand harsh environments
Increased motor life
High acceleration
High power/weight ratios
Sterilization (available in slotted designs)
