BryleeDrive® HighAcc 6mm – Type 1
Two degrees of freedom in the x- and y-direction, and this with an outer diameter of just 6.5 mm – the ultra-compact BryleeDrive® HighAcc 6mm – type 1.
Both axes of the micro positioning system can easily be operated in an open loop control, as each is driven by stepper motors with 20 steps per rotation.
At the core of this multi-axis micro system are zero-backlash MaalonDrive® gears with a reduction ratio of 120:1.
Benefits
1) Compact build up
2) Preloaded ball bearing
3) Robust control without feedback system
4) Zero backlash at high speed
5) 2 linear degrees of freedom

With momentary peak torque or momentary peak force, the elastic deformations of the teeth are still small enough that no tooth meshing problems occur and proper function is ensured.

With drive systems, the motor torque may, in some cases, not be adequate for overcoming the running torque of the complete system at momentary peak torque or momentary peak force. In drive systems, the motor torque may not be sufficient to generate enough torque to meet the permissible momentary peak torque or momentary peak force.

P-102:The maximum speed of the motor describes the speed before mechanical damages occur to the commutator, the rotor or the bearing.
Maximum speed of motor
n

P-103
x
P-103:Describes the step frequency at which the rotor can experience resonance vibrations while the motor is operated under no load. It is recommended that this frequency be avoided in normal operation and that the motor be started at a higher frequency or that half- or micro-steps be used. Additional inertial masses, e.g., through a gear, reduce the resonance frequency.
