Stepper Motors
A stepper motor (sometimes referred to as a step motor or stepping motor) is a motor with windings in the stator and permanent magnets attached to the rotor. It provides fixed mechanical increments of motion; these increments are referred to as steps and are generally specified in degrees. Stepper motors are ideal for applications that require quick positioning over a short distance. This technology allows for the use of an open-loop controller, which simplifies machine design and lowers cost compared to servo motor systems.
How Stepper Motors Work:
A step motor, in conjunction with a stepper drive, rotates in predefined angles proportional to the digital input command (stepper) pulses. A typical full-step system achieves 200 steps per revolution, this equates to 1.8º per full step. The motor’s position can be commanded to move and hold at a step without any position sensor for feedback (an open-loop controller), as long as the motor is sized to the application in terms of torque and speed.
Stepper motors can also make fine incremental moves 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.
Stepper Motor Advantages
- Provide acceleration torque equal to running torque and require no maintenance
- Speed can easily be determined and controlled by remembering speed equals steps per revolution divided by pulse rate.
- Fast acceleration capability with non-cumulative positioning error
Stepper Motors Disadvantages
- 丢失同步导致位置误差
- Resonance affecting motor smoothness
- Limited operation at high speeds
- Running hot
- Can stall with excessive loads
Stepper Motor We Carry:
AC Synchronous Stepper Motors
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步进电动机
A range of hybrid stepper motors with frame sizes from NEMA 8 to NEMA 66. All NEMA stepper motors are available in 4, 6, or 8 lead configurations for bipolar or unipolar operation. In addition to the standard configuration, our NEMA stepper motors can be designed and manufactured according to the special requirements of the customer.
NEMA Hazardous Duty Stepper Motors
适用于第1级第1组，D组位置。它们可在NEMA 34和42框架尺寸（90和110毫米）中提供，并提供最小的固定扭矩，从1.27到9.82 N-M（180至1390盎司）。所有防爆的步进电动机均以双极或单极操作的4、6或8铅配置提供。除标准配置外，这些危险的位置电动机还可以根据客户的特殊要求设计和制造。
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
使用专有制造工艺，该工艺在转子驱动螺母和不锈钢ACME铅螺钉中结合了工程热塑性塑料。这使线性执行器比其他线性执行器中常用的V-Thread和青铜螺母配置更安静，更高效，更耐用。与传统的青铜螺母风格相比，运动寿命的改善超过10倍 - 它不需要维护，也不会影响成本。
Tin-Can Motors
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.
Washdown Stepper Motors
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.
