Direct drive motors
Direct drive technology eliminates backlash, reduces the number of mechanical components, and provides a stiff mechanical system for highly dynamic applications. • High torque and High speed High-torque operations are realized without gears with an instantaneous peak torque of 6 Nm to 600 Nm. High-speed operations reduce the cycle time. (Maximum motor speed : 250 / min to 500 / min) • High precision High-precision indexing of 1,000,000 pulses per rotation (P/R) is available. High-resolution encoder(20-bit):1,048,576P/R No backlash results in high-precision, high-speed operation with short settling times. High accuracy in torque control is enabled by current control algorithms with conversions for the d-q axis. • Compact The size of the drive section in the machine is reduced because of the motor design. Less space is required for installation because hollow space in the motor can be used for wiring and piping. • Easy Smooth and noiseless drive Use of a serial encoder reduces the amount of wiring. The gearless drive requires no maintenance for lubrication or any inspections for wear and tear. Speed, torque or positioning control is enabled via parameters changes.
