New Brushless DC Motor from STEPPERONLINE

Brushless DC motor or BLDC Motor consists of a motor and a drive. Since it operates automatically, it doesn't need extra starting windings on the rotor and it will not vibrate or lose steps when the load changes suddenly.

STEPPERONLINE BLDC Motor eliminates the carbon brush and slip ring structure, so it can run at low speed and high power. In addition, it is much smaller in weight and volume than brushed DC motors, the corresponding moment of inertia can be reduced by 40% to 50%. The motor has soft start soft stop, good braking characteristics, so it will save the original mechanical brake or electromagnetic brake device. The motor itself has no excitation loss and carbon brush loss, eliminating multi-stage deceleration, the overall power saving rate can reach 20% ~ 60%.

The speed control of dc motor brushless is essential for making the motor work at desired rate. The speed can be controlled by controlling the input dc voltage. When the motor works in normal mode or runs below rated speed, input voltage of armature is changed through PWM model. When the motor is operated above rated speed, the flux is weakened by means of advancing the exiting current.

Brush Motor Vs. Brushless Motor
Brush motor and brushless motor have a lot in common but they are structurally opposed.

The rotor of the brush motor is coil winding and connects to output shaft, then its stator is made of permanent magnet materials. While the rotor of the brushless motor is made of permanent magnet materials connecting to the output shaft and the shell, its rotor is coil windings. It has no commutator brush which is used in brush motor to alternately transform the electromagnetic field and that's why it is called brushless motor.

Compared to brush motors, brushless motor has less interference to the controlling devices since it has no brushes. It can move smoothly with low noise and it is easy to maintain.

STEPPERONLINE provides highly genuine BLDC motors or brushless DC motors with best quality and price. You can find a motor with smaller size but stronger output, less noise and vibration with a wide speed range here. If you don't know which motor to choose, please don't hesitate to contact us, we are prepared to give you the most suitable recommendation at any time.

Schmalz Technology Development - Vacuum Generation without Compressed Air - Flexible and Intelligent

• Vacuum generation that's 100% electrical; • Integrated intelligence for energy and process control; • Extensive communication options through IO-Link interface; Schmalz already offers a large range of solutions that can optimize handling process from single components such as vacuum generators to complete gripping systems. Particularly when used in autonomous warehouse, conventional vacuum generation with compressed air reaches its limits. Compressed air often is unavailable in warehouses. Schmalz therefore is introducing a new technology development: a gripper with vacuum generation that does not use compressed air. The vacuum is generated 100% electrically. This makes the gripper both energy efficient and mobile. At the same time, warehouses need systems with integrated intelligence to deliver information and learn. This enables the use of mobile and self-sufficient robots, which pick production order at various locations in the warehouse. Furthermore, Schmalz provides various modular connection options from its wide range of end effectors in order to handle different products reliably and safely.
