5-Phase Microstepping Driver

Higher Torque

Through revisions to the motor winding design and a high-efficiency driver circuit design, the performance of the 5-phase stepper motors has been brought to their full potential, resulting in significant increases in torque in all speed ranges. Torque in the 500 r/min range has increased by 85% compared to conventional products.

Vibration Comparison

Reduced Vibration

The fully digital-controlled microstep driver has further improved the low vibration and noise reduction factors.


High Positioning Accuracy

In general, stopping accuracy tends to be lower during microstep operation* than full step operation and this effect is more noticeable in a 2-phase 1.8° motor. In this situation, using a CVK Series 5-Phase 0.72°/0.36° stepper motor enables a higher positioning accuracy.

*Max. resolution 125000 P/R

High Positioning Accuracy

Common Driver Size Offers Flexibility in Motor Performance

The size, installation and I/O connectors for the CVK Series 2-Phase and 5-Phase drivers are the same. Because of this, it is easy to evaluate and select the proper package for your specific application.

Selectable Step Angle and Run Current Control

The CVD driver has a step resolution switch to allow for matching the input pulse frequency of the controller. Simply use the step angle setting switch to set the input pulses desired. Output pulses are theoretical values as the Smooth Drive feature ensures maximum step performance operation of the stepper motor. The Smooth Drive microstepping control will still be utilized.

Smooth Drive is a function to achieve lower vibration and noise at low speed operation without changing the step angle setting. This function divides the step angle automatically in response to the pulse signals. There is no need to change the setting of the pulse signals (speed, number of pulses) on the controller side. Set the smooth drive function with the OFF/SD selection switch.

Driver Switches

Run Current

The motor current for when inputting pulses (operating current) can be changed with the RUN Current switch. If the load is small and there is an ample allowance for torque, motor temperature rise can be suppressed by setting a lower operating current. The operating current is a value in which the operating current rate is multiplied by the rated current (100%). Minimum current is 25% of rated and selectable in 5% increments.

The CVD Driver can also be used with lower amperage stepper motors. Use the Run Current Selection Switch to match the motor current ratings.

Standstill Current

When the motor stops, the current cutback function will be actuated to lower the motor current to the standstill current. The driver standstill current rate can be switched between 25% and 50% using the STOP switch. When setting the switch to the OFF side, the standstill current rate will be set to 25%. Then setting the switch to the ON side, the standstill current rate will be set to 50%.

Alarms

Monitor the driver performance for early detection of any abnormalities. All CVD drivers have built in alarms to alert when there is a problem. The alarms are both a blinking LED and an Alarm signal to an upper controller. Alarms range from Overheat, Overvoltage, Overcurrent to EEPROM error and CPU error.

PKP Series 5-Phase Stepper Motors

The PKP series stepper motor offers balanced performance enhanced by high torque, low vibration and low noise.

  • 0.72° (500 pulse/rev) & 0.36° (1000 pulse/rev)
  • New Pentagon Winding

SCX11 Universal Controller

universal controller

The SCX11 is a highly-functional and sophisticated controller equipped with program editing and execution functions. Use the SCX11 as a stored program controller to connect to any of Oriental Motor's standard pulse input drivers. The SCX11 is also able to control the motor via serial communications such as USB, RS-232C and CANopen. Accepts encoder inputs.

Driver Cable Set

Driver Cable Set

As an accessory for DC input drivers, lead wires with a connector are available. These lead wires allow for easy connection of the motor, power supply and input/output signals. The connection cable set includes three connection cables (for motor, power supply and input/output signals).

Operating Principles of a 5-Phase Stepper Motor


With a higher resolution you get a smaller step angle, which in turn reduces vibration. Since the step angle of the 5-phase stepper motor is 2.5 times smaller than the 2-phase the ringing, vibrations, are much lower.

5-Phase Stepper Motor Structure


While the 2-phase motor moves 1/4 tooth pitch each phase. The 5-phase, because of its construction, moves 1/10 of a tooth pitch. Since the pitch is still 7.2°, the step angle is 0.72°. Simply based on construction, the resolution of the 5-phase has 500 steps per revolution versus the 2-phase with 200 steps per revolution. The 5-phase offers a resolution 2.5 times better than that of the 2-phase.
