• Reasons for Turning to Slotless DC Motor Technology
  by brush-commutated products, due in part to dramatic reductions in the cost and size of. electronic components and advances in motor design and manufacturing. ./e31c53ba-a077-486e-822c-5e7f1145584c REASONS FOR TURNING TO. SLOTLESS TECHNOLOGY. When first introduced, brushless DC motors...
• DC Motors
  Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of rotation. Continuous operation of dc motors is commonly available over a speed range of 8:1...
• Oceanic probes float free -- thanks to a brush-dc motor
  With the growing interest in brushless and permanent-magnet synchronous motors, one might get the feeling that the venerable brush-dc motor is on the decline. Not so for a high-tech research probe that relies on brush-dc motors to keep it afloat as it drifts along in the sea. Scientists involved...
• Selecting DC Motors
  with electronic switching. Brushless dc motor controllers require a position feedback signal from a sensor inside the motor. The sensor ensures that excitation to the electromagnetic armature field always leads the permanent-magnet field to produce torque. Power transistors drive the armature...
• Coreless DC Motors
  . Because the core is ironless, its low mass allows more rapid acceleration and deceleration than any other class of dc motor. Other benefits gained by eliminating the iron core include the absence of magnetic fields acting on the laminations. This interaction in conventional motors appears as torque...
• China ups the motor ante
  China's motor manufacturers are well versed in small, standard motors. Now they're setting their sights on steppers and servos. Chinese manufacturers have been making motors for years. The majority of these have been small ac and dc units for electric tools, toys, and other high-volume applications...
• Cowern Papers: Motor Basics
  the. requirements of the application. In general, the frame size gets larger with increasing. horsepowers or with decreasing speeds. In order to promote standardization in the. motor industry, NEMA (National Electrical Manufacturers Association) prescribes. standard frame sizes for certain dimensions of standard...
• Selecting Dc Brush and Brushless Motors
  mechanical commutation (dc motor with brushes) and electronic commutation (brushless dc motor, BLDC). Considerations of life expectancy, reliability, simplicity of actuation, and maximum speed play a role in this process. Special environmental conditions such as operation in a vacuum or the ability...
• Power and efficiency drive motor selection
  . In the case of dc brushless and brush-type motors, the first step determines the motors' power output from Most catalogs list the motor's output power, so matching the results of the calculation to an available motor is straightforward. The second step determines the motor efficiency, represented...
