Normalized Torque (%) x 0.5 x 1 x 1.5 x 2 Rated Current The unique electromagnetic characteristics of disc magnet motors permit them to operate well below any saturation of the magnetic circuit, where torque is truly proportional to current. By current boosting, performance can momentarily be pushed well above nominal values. Iron losses comparison DM/Hybrid same torque, losses due to magnet flux only.

This gives low iron losses and more torque at high speed.
Slotted BLDC A World of Applications B BLDC Motors The Miniature Brushless DC Motor Technologies Conventional DC motors use a stationary magnet with a rotating armature combining the commutation segments and brushes to provide automatic commutation. In comparison, the brushless DC motor is a reversed design: the permanent magnet is rotating whereas the windings are part of the stator and can be energized without requiring a commutator-and-brush system. Therefore this motor type achieves very long, trouble-free life even while operating at very high speeds. Construction of three BLDC motors: 22BT (with the tube rotating with the magnet, right), 26BC, slotless iron structure (left) and a B09 motor with slotted iron structure (center) Concept Detail Motor Characteristics Advantages for the Application DC device Brushless design Static winding attached to motor housing Versions without position sensor Versions with hall effect sensors DANAHER MOTION is a registered trademark of Danaher Corporation.

Tel One technology uses a self-supporting cylindrical ironless coil made in the same winding technique as for our ironless rotor DC motors: this is called the BLDC motor, slotless iron structure. The rotor is a cylindrical two-pole magnet, the stator tube is made of iron laminations. With this construction a uniform and constant airgap is obtained. If the tube is fixed to the magnet and rotates with it, iron losses are avoided. The other technology is called BLDC motor, slotted iron structure. The iron cores are part of the housing. The rotor Essentially linear torque/speed curve proportional to current and speed proportional to voltage Life is not limited by brush wear but only by wear on ball bearings Possibility of speed and position control Very long life, high reliability, insensitive to environment (no arcing), to shocks and to vibration Improved heat dissipation Overload capability Typically used in spindle applications Typically used in applications with high variation of speed or load is a multiple-pole magnet. The position of the rotor field is continuously monitored to ensure correct timing of the commutation (switching of the current in the windings through power transistors). Three options for supervising the rotor position are proposed. The first one uses no sensor inside the motor but derives the information by analyzing the shape of back-EMF. It is easy to implement and recommended mainly for high speed continuous operation. Another option are Hall sensors built into the motor, signalling the rotor field strength. Finally, an encoder or resolver may be added to the motor externally. It provides very high resolution and allows the BLDC motor to perform anything a DC with brushes can do but without the drawbacks of a mechanical commutation system.
