"ASTRO-E 250" CONTROL * MOTOR
* SPINDLE
| ASTRO-E 250 control
features many high-grade electronic circuits
including gentle-start circuit, quick-stop
function, and feedback circuit which keep
the rotating speed constant even under
load. The high-efficient circuit breaker
offers protective functions such as reset
lamp indication and rotation stoppage.
(Protection is automatically release be
turning OFF the power switch.) If the
MANU-AUTO selector switch is turned to AUTO,
the start and stop control of the motor, and
the stop signal of overload state can be
detected from the sequence control terminal. |
- The speed is indicated on
digital display panel.
- MANU/AUTO selector switch (At
AUTO position, the rotation and stop,
control of the motor, and the stop
signal at an overloaded state can be
detected from the sequence control
terminal.)
- Weight 7lb. 1.8oz.;
- Power Source 120V,, 230V.
50/60Hz
- Power Consumption 75W
- Dimensions W8.86"D7.68"H3.82"

Brushless
Achieved excellent durability
and high reliability by the adoption of
high-speed brushless motor, which
eliminate the nuisance of brush
replacement and maintenance.
High Output Power
210W.
Smooth Rotation
Absence of slot in and rotation
of the armature rotor unit are detected
by photocoupler and interrupter rotor,
while feedback signal of 48 pulses per
rotation results in smooth rotational
motion with little vibration from
low-speed to high-speed.
Withstands 5,000
Hours of Continuous Use
(by NSK's
internal standard load tests)
- Brushless motor
without carbon brush (no contact)
minimized the wear of motor and
provides long service life.
- Due to the brushless
construction, electric jam and other
noises are reduced.

| A pair of precision ball bearings is
assembled on the both front and rear sides of
the spindle that is designed to adjust the
radial and thrust plays to a minimum. This
spindle can be used for small-diameter drilling,
slitting brass and aluminum (with Ø30 Metal Saw)
and grinding with a lathe. Wide variety of
Collet Chucks are available for NR-302. |
