Detachable Digital
Operator
The digital operator, which serves as both a data
setting unit and a display, can be detached from the driver and used
at a location as far as 5 m (16.4 ft.) away using an optional
remote-control kit. Use the digital operator as a handy operation
unit or a display outside the distribution panel. [The digital
operator conforms to IP65 when the remote-control kit is used. (sold

New
Expanded BX Series BLDC Speed Control Systems
Oriental Motor announces the expansion of our BX Series
BLDC speed control systems. The new systems are RoHS-compliant
and feature the new high-power, long-life parallel shaft and
flat hollow shaft gearheads. The
new gearheads have a rated life of 10,000 hours (twice that of
our standard gearheads).The BX Series brushless DC motor and driver
packages offer high performance and high function.
-

Speed Control during
Vertical Drive
The motor with an electromagnetic brake
enables stable speed control even during vertical drive
(gravitational operation). When the power is turned off, the
motor stops instantly to hold the load in place. The
electromagnetic brake is automatically controlled via the
driver in accordance with ON/OFF of the operation command
signal. | |

MOTION CONTROL QUESTIONS? ASK AN
ORIENTAL MOTOR ENGINEER
 |
 |
Oriental
Motor's Engineering Team is just a click away. Send your
motion control questions to Oriental Motor's engineers and we'll
publish their response in an upcoming issue of New
Motion. |
Q: Are
there any concerns using Speed Control products for a vertical
application?
|
A:
Two situations generally
need to be considered.
The first one is how to hold the load under unexpected power
down situation. The
motor will lose its torque if it loses the input power.
This may cause the load moving downward due to gravitational
force unless there is enough friction or system loss (low
efficiency).
However, if you design a system to have large friction or low
efficiency, you may need to size the motor larger.
The system friction or efficiency may change after a period
of operation. Therefore
a magnetic brake motor is recommended for vertical application.
|
|
The
second concern is how to handle the back EMF, Electro-Magnetic-Field
generated during downward operation. The motor
has its magnetic field because of the winding in the stator. If
the motor is back driven by an external force, which is the gravitational
force in this case, it generates a back EMF. This
causes extra energy feedback to the controller and it may damage the
controller. The
gravitational force also pushes the motor speed to run faster. If
the speed is pushed faster than the permissible speed, then, the driver
senses it as an abnormal situation, and alarms out. Therefore,
it is recommended to use a driver which can handle back EMF for vertical
applications.
With
considering the two situations, Oriental Motor recommends the two product
types; the BX brushless DC speed control series and the BHF
AC speed control series. These
series has the options for electromagnetic brake preassembled on the motor
and the separate regeneration unit to use with the
controller.
Q: I want to
control the speed of two motors to be the same. I need to control the
speed on both sides of the conveyor. How do I do this and what products do
you recommend?
A: There are several products
that can do parallel operation with different ways to control the
speed.
The following are some examples which may
vary depending on the product.
