The e-TORQ™ Direct Drive Brushless
DC Motors employ a unique electromagnetic design to improve
efficiency, minimize size, and maximize torque. The e-TORQ
motors are ideal for OEM’s where high torque, compact design and
enclosed construction are critical. Bodine Electric’s
engineering team is available to work with OEMs to customize
this product to fit most applications.
The ironless stator of e-TORQ motors eliminate iron saturation
common to most other types of motors, and allows the motor to
run smoothly at extremely low speeds. The lack of iron
saturation provides maximum torque linearity, meaning that
torque is extremely consistent from very low to very high speeds
without any cogging or velocity fluctuations (ISV). The high
torque capability allows for the elimination of costly gearboxes
and removes the risk of lubricant leaks. The e-TORQ motors are
available in widths of less than four inches, with diameters
ranging from 7 to 14 inches and larger. The standard 14-inch
motor delivers more than 200 lb-in. at speeds of up to 1,200
rpm.
What makes the e-TORQ™ motor so unique
• Iron free stator eliminates motor cogging (Detent Torque)
which improves low speed control
• No iron saturation for maximum torque linearity
• No lamination core loses that yields very high efficiency
• Ten times peak torque is available
When combined with a high performance digital amplifier, the
Bodine e-TORQ system becomes an easy-to-set-up, high performance
motion control solution. e-TORQ motors can eliminate the need
for a planetary gearhead, or other mechanical gear reduction
methods.
