CVK-SC Series Speed Control Stepper Motors

CVK-SC Series Speed Control Stepper Motors

CVK-SC Series Speed Control Stepper Motors

The CVK Series SC speed control system offers a simple configuration consisting of a stepper motor, driver and programmable controller. The operating speed, acceleration and deceleration time, running current can be set via the driver switches, and simply turning the FWD (RVS) input to ON or OFF allows for easy control.

  • No pulse generator needed
  • 2 speed settings are possible
  • Compact and high torque stepper motor
  • Improved stop position repeatability
  • Maintains torque even when stopped
  • Continous duty is possible
  • *Motor cables required (sold separately)

Simple Speed Control

Simple System Configuration to Control I/O

Simple configuration consisteng of stepper motor, driver and programmable controller. The operating speed, acceleration and deceleration time and running current can be set via the driver switches. Simply turning the FWD (RVS) input to ON or OFF allows for easy control.

Speed Control Stepper Motor System

2 Individual Speed Settings are Possible

The driver can be set to 2 individual speed and can be easily controlled externally.

2 Speed Settings

Maintains Torque When Stopped

Motor current is supplied when stopped so torque is still generated. This provides load holding capability (holding force is 50% of max. holding torque).

The Motor can be Downsized Thanks to the Use of Compact, High Torque Motors

Because a stepper motor provides high torque at low operation speeds it can be used without a gearhead. This allows for downsizing of the motor and decreasing the overall size of the equipment as compared to induction motors with almost identical speeds.

Downsizing the motor

When the Operating Input is Constant Stop Position Reliability is Improved

When the motor is stopped, even if the load weight is changed, if the operating conditions are the same the deceleration travelling amount does not change due to inertial load or frictional load. This allows for improvement of the stop position repeatability.

Operating Input


Continuous Duty is Possible

For continuous duty, the below operating conditions are required and the motor case temperature needs to be less then or equal to 100°C (212°F). 

When the ambient temperature is 50° C (122°F):

2 types of drivers are available.

Speed Control Driver Products


 

Motor Cables (*Required)

Motor Cables (*required)

These cables are used to connect the connector-coupled motor with the driver. Because there are connectors on both sides the motor and driver can be connected directly.

 

Flexible Couplings

Flexible Couplings

Flexible couplings provide simple connection to drive shaft and reduce vibration and backlash from the motor.

 

Mounting Brackets

Mounting brackets are convenient for installation and securing a stepper motor or geared stepper motor.

 

 

 

Driver Cables (Optional)

Driver Cables

These cables are used to connect the driver to I/O Signals, DC Power Supply and Motors (lead type).


Driver Mounting Bracket

Driver Bracket

This is a DIN Rail mounting bracket for drivers with installation plates.

 

Driver Cover

Driver Cover

This cover provides protection for the driver and prevents accidental contact. For use with right-angle type connector type with installation plate.
