Are there ways to keep the stepping motor temperature down?
- Adjust the operating current (a margin of torque must be present since lowering the current decreases the torque). This lowers heat generation during operation. Use the driver functions.
- The Hold-Off and Automatic-Current Down functions decrease heat generation when the motor is stopped.
- Install the motor on a metal plate with good sinking capabilities.
Is there any way to decrease vibration during step motor operation?
There are several ways:
- If using 2-phase, switch to 5-phase. For the ultimate smoothness, use a 5-phase microstepping driver unit, such as an RK or CRK, to decrease vibration. Adjust the operating current.
- Vibration can be decreased by decreasing the torque.
- Use a geared motor. Geared motors decrease the translation of vibration. Use a clean damper.
- Vibration is absorbed by internal inert bodies and silicon gel.
What is the replacement for your older PH 2-phase stepping motors?
What is the step angle for your PK 2-phase stepping motors?
PK motors come in two basic step angles: Standard (1.8°/step) and high-resolution (0.9°/step). The high-resolution type is indicated by an "M" in the part number.
Does Oriental Motor have a standard driver for use with its 2-phase stepping motors?
At how high a temperature can stepping motors be used?
The permissible temperature for the coils is 266°F (130°C), since the insulation of the motor is Class B. The motor can be used if the motor surface temperature is 212°F (100°C) or less. Try to use the motor at the lowest temperature possible and mount it to a metal plate that is a good heat conductor, since heat does affect the life of the motors ball bearings. Type A insulation 221°F (105°C) is a UL/CSA certification condition. When applying for UL/CSA certification as a set, use with a motor case surface temperature no higher than 167°F (75°C).
Why does the motor move a little when the power is turned on?
Is it all right to machine the motor shaft?
When the shaft is machined, some impact may be felt by the ball bearings within the motor. Therefore, machining is not recommended. On a similar note, do not disassemble the motor. (Disassembling the motor will not only dramatically lower performance, but it can also cause it to cease functioning if foreign matter gets inside.)
How far apart can the driver and controller (pulse generator) be?
What are the differences in performance and wiring between Unipolar & Bi-Polar configurations?
Refer to the Unipolar/Bipolar Connection Diagram.
What is the difference between half-stepping a std. 2-phase motor and full-stepping a high-resolution type motor?
How do stepper motors perform in very hot environments?
We recommend a maximum ambient temperature of ~50°C. For extreme cases, please consult our Tech Support Center at 1-800-922-6646.
What is the difference between a high-resolution motor and a standard 2-phase motor?
What is the difference between resolution and accuracy?
Resolution is based on the degrees of motion per step. Accuracy is dependent on the mechanical precision of the stator and rotor teeth and the winding balance. Error is non-cumulative.
Will a line-driver pulse output work with Oriental motor driver?
Can I use one sensor to home with your controllers?
Yes. For the Alphastep Plus controller, you will need to set HOMETYP = 4 (3 sensor mode). For the EMP controller, you will also need to set SEN = 3 (3 sensor mode). Connect your home sensor to the HOMELS input, and make sure you set the right direction to home.
