Direct drive brushless DC servomotors employ a novel electromagnetic design to improve efficiency, minimise size and maximise torque.
New from Bodine Electric Company, e-Torq direct drive brushless DC servomotors employ a novel electromagnetic design to improve efficiency, minimise size and maximise torque.
The e-Torq motors are ideal for OEMs where high torque, very compact design, enclosed construction, and economy are necessary.
Bodine has assembled a team of engineers available to work with OEMs to customise 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 can allow the elimination of costly gearboxes and remove the risk of lubricant leaks.
The e-Torq motors are available in widths of less than 2in, with diameters ranging from 7 to 14in and larger.
They deliver more than 11Nm at speeds up to 6000rev/min, all with a wide range of shaft, through hole and mounting arrangements.
