Stepper Motors
步进电机（有时称为步进电机或步进电机）是具有连接到转子的定子和永磁体中的电动机。它提供了固定的机械增量;这些增量称为步骤，通常以度为单位指定。步进电机非常适合需要在短距离内快速定位的应用。该技术允许使用开环控制器，该控制器简化了与伺服电机系统相比的机器设计和降低成本。
How Stepper Motors Work:
步进电机与步进驱动器结合，以与数字输入命令（步进）脉冲成比例的预定义角度旋转。典型的全步系统每次旋转实现200个步骤，这相当于每一步1.8º。可以命令电动机的位置以在没有任何位置传感器的步骤中移动和保持用于反馈的步骤（开环控制器），只要电动机就在扭矩和速度方面的应用范围内。
步进电机也可以细增量移动s and do not require a feedback encoder (open Along with excellent low speed/high torque characteristics without gear reduction, stepper motors can also be used to hold loads in a stationary position without creating overheating.
步进电机优势
- 提供等于运行扭矩的加速扭矩，无需维护
- Speed can easily be determined and controlled by remembering speed equals steps per revolution divided by pulse rate.
- 具有非累积定位误差的快速加速度能力
步进电机缺点
- Loss of synchronization resulting position error
- 影响电机平滑度的共振
- Limited operation at high speeds
- Running hot
- 可以与过多的负载摊位
Stepper Motor We Carry:
交流同步步进电机
With synchronous motor technology, speed is directly proportional to AC input frequency – for example, at 120 Vac, 60 Hz, an AC synchronous motor will turn at 72 rpm. This speed can be varied by varying the frequency, although most applications simply use gearing or a belt- or chain-drive system to achieve the desired load speed.
Integrated Stepper Motors
Fuse step motor plus drive and control components into a single device. Integrated steppers offer a space-saving design that reduces wiring and saves on cost over separate motor and drive components.
NEMA Stepper Motors
一系列具有框架尺寸的混合步进电机，从NEMA 8到NEMA 66.所有NEMA步进电机都有4,6或8个用于双极或单极操作的铅配置。除标准配置外，我们的NEMA步进电机还可以根据客户的特殊要求设计和制造。
NEMA Hazardous Duty Stepper Motors
Suitable for use in Class 1, Division 1, Group D locations. They are available in NEMA 34 and 42 frame sizes (90 and 110 mm), and provide minimum holding torques from 1.27 to 9.82 N-m (180 to 1390 oz-in). All explosion-proof stepper motors are available in 4, 6 or 8 lead configurations for bipolar or unipolar operation. In addition to the standard configuration, these hazardous location motors can be designed and manufactured according to the special requirements of the customer.
Stepper Gearmotors
Combine some of our most popular 2-phase hybrid 1.8° step angle NEMA 17 and 23 frame motors with offset spur geaheards to create simple but strong gearmotor solutions for applications requiring high torque at low speeds. The gearheads utilize high-strength steel and precision hobbed gears in one-piece clusters, housed inside a high-temperature, molded composite housing.
Stepper Motor Linear Actuators
Use a proprietary manufacturing process, which incorporates engineering thermoplastics in the rotor drive nut and a stainless steel acme lead screw. This allows the linear actuator to be much quieter, more efficient and more durable than the v-thread and bronze nut configuration commonly used in other linear actuators. Motor life is improved more than 10 times over the traditional bronze nut style – and it requires no maintenance and does not affect the cost.
锡罐电机
Tin-Can Step Motors (also known as Can-Stack Step Motors) are 2-coil permanent magnet motors. When poles are magnetized by electric pulses applied to the coils, they attract the permanent magnet rotor core in reverse polarities, thereby starting rotation.
洗涤步进电机
Washdown & Food Grade Stepper Motors are conventional hybrid step motors which are dust proof and resistant to low pressure water jets. They are ideal for applications in wet factory environments such as the food and beverage industry or outdoor use. Key features include a nickel-plated brass cable gland, sealed laminations, a front shaft contact seal and an optional IP65 rated encoder cover for use with products that require feedback.
