MOTOR CYLINDER

1 Product Description
1-1 General
Introduction
The Motor cylinder is completely enclosed structure, consisting of an overload safety device
(automatic stroke setting) by actuation of a compression spring, a highly efficient lead screw,
a fully closed type motor combined with a precision reduction gear unit.
Therefore, careful handling of the Motor cylinder is necessary.
Inspection and checks
- Does the nameplate match the order?
- Is there any damage during transportation?
- Are all tightening bolts fastened with sufficient force?
- In case there are any troubles, please check the model, serial number, situation and contact
us immediately.
1-2 Operation principle
The screw shaft rotates by the rotation of the motor.
At this time, the Piston rod assembled with the nut operates a linear restraining motion within
the set stroke range, and the load reciprocates in forward and reverse rotation of the motor.
According to type, the required movement speed can be obtained by adjusting the pitch of the
screw and the reduction ratio of the reduction gear device.
1-3 Motor cylinder used
Used for elevating and lowering, reciprocating, compression and traction by linear motion
Compressing Stop
It can also be used for devices requiring continuous compressive force or pulling force by
the operation of a built-in spring, and can be safely stopped without mechanical overload by
the operation of the spring and the limit switch.
Retaining Load
When the load is applied even after Motor cylinder in operation is stopped, there are two
ways in which the load from the stop position can be maintained.
First, the way to keep the screws locked on the brakeless type.
Second, the way of maintaining the load by the braking force by the brake attachment.

Arbitrary Stroke Setting
In the type with an external or internal limit switch set, the stroke can be arbitrary set and
used by adjusting the position of the limit switch operation cam within the entire stroke range.
Inching Movement
When the Motor cylinder is installed or used, the inching movement on the stroke is also
available for every of our products.
In the type with no brake, there is some difficulty in stopping at the correct position due to
the inertia of the rotor inside the motor.
