What is a Stepper Motor?

A stepper motor is a type of brushless DC motor that divides a full rotation into a number of equal steps. This unique characteristic allows precise control over the motor’s angular position, making it highly suitable for applications requiring accurate motion control. Stepper motors operate by receiving pulses from a controller, with each pulse moving the motor a specific step, leading to excellent position stability.

Understanding the 86mm Stepper Motor

The 86mm stepper motor is defined by its frame size—86mm in diameter. This motor size is commonly used in applications requiring higher torque, greater precision, and more significant power. With varied specifications, the 86mm stepper motor can deliver different performance characteristics, such as holding torque, step angle, and current ratings, catering to diverse applications.

Dimensions and Physical Characteristics

The physical attributes of the 86mm stepper motor, such as its weight and length, play a pivotal role in its integration into devices and systems. Generally, the 86mm stepper motor weighs between 2.5 to 5 kg, depending on its design and materials. Its compact nature allows it to fit into tight spaces while still delivering maximum performance.

Types of 86mm Stepper Motors

There are two main types of 86mm stepper motors: bipolar and unipolar. Bipolar motors have two coils and provide higher torque, while unipolar motors include a center tap and are easier to control. Understanding these differences is essential in choosing the right motor for your application.

Key Specifications of 86mm Stepper Motors

Understanding the specifications of the 86mm stepper motor is crucial for evaluating its performance and suitability for specific applications. Here’s a detailed look at the key specifications:

1. Step Angle

The step angle refers to the degree of rotation for each step. Common step angles for 86mm motors are 1.8 degrees (200 steps per revolution) and 0.9 degrees (400 steps per revolution). A smaller step angle allows for finer resolution in movement.

2. Holding Torque

Holding torque is the maximum torque the motor can maintain when stationary. For 86mm stepper motors, this can range from 1.2 to 5.0 Nm. Higher holding torque is crucial for applications involving vertical loads or machinery requiring consistent positioning.

3. Current Rating

The current rating determines the amount of electrical current the motor can handle. A typical 86mm stepper motor may have a current rating of 2A to 5A per phase. Selecting the motor with the appropriate current rating ensures optimal performance without overheating.

4. Voltage Rating

Voltage rating plays a significant role in stepper motor performance. While stepper motors are often rated at 12V or 24V, it’s crucial to match the motor with the correct voltage supply to avoid damage and ensure efficient operation.

5. Rotor Inertia

Rotor inertia affects how quickly the motor can accelerate and decelerate. Lower inertia allows for faster response times, making it suitable for applications requiring rapid movements.
