9 5 phase Stepper Motor Manufacturers in 2023
This section provides an overview for 5 phase stepper motors as well as their applications and principles. Also, please take a look at the list of 9 5 phase stepper motor manufacturers and their company rankings.
What Is a 5 Phase Stepper Motor?
A stepper motor is a motor whose rotation angle and speed can be controlled by pulse signals and is used when accurate positioning is required. Among stepping motors, those with a movement angle of 0.72° per pulse are called 5 phase stepper motors.
Uses of 5 Phase Stepper Motors
Stepper motors have the following main features:
- Compact and capable of generating high torque, allowing frequent starting and stopping.
- Since a holding force is generated even when the motor is stopped, they can maintain the stopped position even without a mechanical brake.
- Compared to servomotors with equivalent mounting angle dimensions, they can drive larger inertial loads.
In addition to these features, 5 phase stepper motors are used to drive XY stages for microscopes because of their high-precision positioning capability.
Principle of 5 Phase Stepper Motors
Stepping motors are mainly composed of a "rotor" and a "stator.
- Rotor
The rotor is the rotor inside the stepping motor, which is made of iron divided into two parts, with a permanent magnet sandwiched between the two parts, each of which is magnetized into N and S poles.
The outer circumference of each rotor of 5 phase stepper motors has 50 small teeth cut at a pitch of 7.2° each, and they are assembled with the small teeth shifted by half a pitch from each other. - Stator
The stator is located outside the rotor and consists of multiple windings. It consists of one set of opposing positions across the rotor, each of which is denoted as a "phase. Basically, they are often represented by letters of the alphabet, such as phase A, phase B, etc.
For the above components, 5 phase stepper motors can be operated by the following procedure.
- Pass a current through phase A of the stator and magnetize it to the S-pole. At this time, the small teeth of the phase-A magnetic pole and the small teeth of the rotor on one side attract each other. On the other hand, the small teeth of the adjacent phase-B pole and the small teeth of the other rotor are displaced by 0.72° at this time.
- Next, a current is applied to phase B of the stator to magnetize it to the N pole. Then, the small teeth of the B-phase magnetic pole and the small teeth of the rotor that were 0.72° out of alignment in step (1) stop facing each other.
Thus, switching from phase A excitation to phase B excitation causes the rotor to rotate 0.72°.
In terms of electrical signals for control, "one cycle of power ON/OFF is one pulse," and when one pulse is input, the motor output shaft rotates by one step angle (0.72° for 5-phase).
Wiring for 5 Phase Stepper Motors
The characteristics of 5 phase stepper motors vary depending on the wiring method. When designing a device, the wiring method should be considered to obtain a balance between cost and performance that is appropriate for the device.
Wiring methods include star wiring, pentagon wiring, and new pentagon wiring.
5 Phase Stepper Motors Control
Stepper motors maximize their characteristics by setting the rotation speed according to time. Setting the rotation speed according to time is generally called an operation pattern. There are two types of operation patterns.
- Self-starting operation pattern
This is an operation pattern in which the motor rotates at the same speed from start to finish. It is called rectangular drive because a graph of speed vs. time forms a square (rectangle). - Trapezoidal drive operation pattern
This is an operation pattern in which the motor rotates at a slow speed at first, then gradually increases in speed, rotates at the maximum speed for a certain period of time, then gradually decreases speed, and then stops. It is called trapezoidal drive because a graph of speed versus time forms a trapezoidal shape.
The rotation speed of a motor is not something that can be set as desired, but is determined by the following factors.
- The characteristics of the motor you choose
- Mass of the object to be moved
- Friction applied to the object to be moved
- Electric power applied to the motor
- How the motor is wired
- How the motor is excited
The characteristics of the motor you choose, especially the rotor inertia, are most important, especially when the motor is used for applications that require rapid movement and rapid stopping.
Difference Between 5 Phase Stepper Motors and 2 Phase Stepper Motors
Stepper motors and servo motors are capable of higher precision positioning than other common motors (such as DC brush motors). In particular, 5 phase stepper motors are generally extremely expensive compared to 2-phase stepping motors. 5 phase stepper motors are chosen because 2-phase stepping motors allow a smaller motor rotation angle per step (the smallest unit of rotation instruction to a motor). The following characteristics are required
When you want to rotate the motor at a very small angle.
When you want to lower the noise level.
