AlphaStep does not
lose synchronism, even when subjected to abrupt load
fluctuation or acceleration. A newly developed
rotor position detection sensor constantly monitors
the motor movement. If synchronism is about
to be lost, closed loop control is used, so there
is no need to worry about loss of steps.
The new rotor-position
detection sensor detects position information of the
rotor, based on change in inductance, as determined
by change in the spatial distance between rotor teeth
and stator teeth. |
|
The motor will normally run
in open loop mode. If
the position deviation of the rotor is ±1.8°, the motor will switch to closed
loop mode to prevent the loss of synchronism and proceeds
to the proper position.

NEW 5-PHASE MICROSTEP SYSTEM
|
The CRK series is a motor/driver
package consisting of a high-performance 5-phase stepping
motor and a compact microstepping driver (offering the Smooth
Drive function). The high-torque type motor together
with the high performance geared types open a new realm
of DC input 5-phase microstepping packages. |
|
|
The driver for the CRK series
achieves microstepping in a compact, lightweight body.
The new IC allows the driver to provide various functions
including:
|
|
| The
Smooth Drive function keeps vibration to a minimum and
automatically controls the motor's microstepping operation
at the same travel and speed as in the full-step mode, without
the operator having to change the pulse input settings.
The
CRK series comes in four frame sizes from 0.79 in. to 2.36
in., as well as three geared motor types. |

The CRK Series is RoHS compliant
in addition to conforming to global safety standards for safe
worldwide operation. It is UL-recognized and also bears
the CE mark as a proof of conformance to the EMC directives. |
|
High-Torque Type
The
high-torque type adopts new technology and torque design. The
motor produces ample torque of approximately 1.3 to 1.5 times the level
achieved by a conventional motor. Providing torque equivalent
to a motor of the next larger frame size, the high-torque type allows
downsizing of your equipment. The motor also adopts a connector
system for easy installation.

Q:
What is the microstepping?
A: Microstepping is a technology
that achieves low resonance, low noise operation at extremely low speeds
by controlling the flow of electric current fed to the motor coil and
thereby dividing the motor's basic step angle into smaller steps.
-
The motor's basic step (0.72°/full
step (5-phase)) can be divided into smaller steps ranging from 1/1
to 1/250. Microstepping thus ensures smooth operation.
-
With the technology for smoothly
varying the motor drive current, motor vibration can be minimized
for low noise operation.
