Delta Line is expanding two of its product lines with the introduction of its 38BLF07 frameless BLDC motor and its Leo B2000 servomotor controller.

Delta Line has experience in designing motion solutions driven by frameless BLDC motors and is now expanding its portfolio with the addition of the smallest member of the family the new 38BLF07 with only 38mm outer diameter. This model will complement the manufacturer’s existing range with sizes 38, 50, 70, 85 and 115 mm available to satisfy various application needs.

The 38BLF07 motor has a length of just 14 mm with a rated torque of 0.1Nm at rated speed of 8,000 rpm and can produce a peak torque of 0.3 Nm. With only 57 g of weight, this motor has been designed to minimize inertia, making it a suitable solution for dynamic movements with high acceleration and deceleration rates.

Delta Line has extended its Leo Drive family with the introduction of the new Leo B2000 drive. This new high-performance closed-loop servo drive controller is suitable for servo and BLDC motors. It has been designed with efficiency in mind and incorporates optimized control algorithms to provide the perfect trade-off between efficiency and performance.

The Leo B2000 drive is the latest generation of servo drives offering best-in-class performance from a compact housing delivering up to 2000 W … and including all the latest technologies required by the market.

Leo’s compact design includes multiple communication ports to support various interfacing methods. Its voltage operating range allows use in various applications, and the small footprint as well as the presence of a heatsink allow the controller to be a valid option for critical-size applications. This controller is provided with several general-purpose inputs and outputs in the logic. By using these inputs and outputs it is possible to implement alarm signals, connect digital sensors, and activate external devices such as LEDs, brakes, actuators, and solenoids.

The Leo servo drive also offers the opportunity to manage a double incremental and absolute multi-turn encoder. Moreover, the safe torque off SIL3 system opens the door to all the safety applications around the world. The new controller can be best used for applications such as automatic guided vehicles, electric vehicles, and industrial production machines. It may be easily combined with all Delta Line’s servo-BLDC motors up to 2,000 W.
