3.2 Stage Heat Dissipation Consideration
The motor heat dissipation mechanism is by convection and radiation to the motor
case, and by conduction through motor’s ‘finger tips’. Hence, the motor and the
Ceramic Driving Strip bases, must both be thermally designed to dissipate 2W each
(per motor’s ‘finger tip’), with maximum temperature rise of 15
°
C.
3.3 Thermal EOP for HR Motor Driven by AB1A,
AB1A-3U, AB2 AB4 Drivers
Figure 9 illustrates motor velocity as a function of the applied driver
command voltage. Allowing up to 30 mm/sec variations, use it as a
reference and as a guideline for expected motor performance:

Figure 10 and Table 1 are designed to help the user determining the
correct envelope of performance and avoid overheating and
damaging the motor.

The motor operates horizontally at room temperature and low duty cycle (< 10%). It interfaces with the
Ceramic Driving Strip (according to Nanomotion Specifications) and a cross-roller high quality slide.
