NEMA步进电机
电气provides 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. Available customizations include a variety of shaft machining options, plus the addition of optional encoders, gearboxes, and brakes. Electromate supplies NEMA steppers throughout Canada’s four distinct industrial regions: the Atlantic Provinces, Central Canada, the Prairies, and the West Coast.

Applications
步进电机在其用途中是多种多样的，但其中一些最常见的包括：
- 复印机
- 3D printing equipment
- Textile machines
- Printing presses
- Gaming machines
- Medical imaging machinery
- Small robotics
- CNC铣床
- 传真机
While these applications are the most common, they’re a fraction of what stepper motors can be used for. Generally speaking, any application that requires highly accurate positioning, speed control, and low speed torque can benefit from the use of stepper motors.

电气sells step motors manufactured by these vendors:
美国国家电气制造商协会vwin德赢线上娱乐(NEMA) defines a set of standards used to dictate tolerances for many products, including step motors. Step motors are categorized by NEMA frame size, such as "size 11" or "size 23" or “size 34”. Generally speaking, a size 11 step motor means the mounting face of the motor is 1.1 inches square; A size 23 step motor is 2.3 inches square; A size 34 step motor is 3.4 inches square, etc.
NEMA standards help provide interchangeability - the ability to switch from one manufacturer to another without having to significantly change mounting brackets, couplings, etc. However, two motors of the same NEMA size may actually differ somewhat among manufacturers. Shaft length and shaft diameter are examples of the differentiation, as is the presence of a flat or a keyway on the shaft which varies from supplier to supplier. NEMA standards do not dictate the number of lead wires or winding impedance, so be sure to consider all specifications carefully before designing in an alternate supplier.
- Parallel connect the lead wires for best torque over the widest speed range
- 如果驱动器可获得足够的电流，则串联将引线电线连接为低速以全扭矩
- Keep motor case temperature below 100 °C. This can be achieved by lowering the motor current or limiting the duty cycle
- Allow sufficient time to accelerate load
- Use a microstepping drive for smoothest motor performance over a wide speed range
- For open loop operation, size the motor with a 30-50% torque margin at speed. Including an encoder in the system and using a Stall Prevention feature may allow operation all the way down to a 0% torque margin
- 不要拆卸电机。将导致电机性能显着降低
- Do not machine shafts without consulting Electromate® first
- Do not disconnect motor from drive while power is applied. Remove power from the drive before disconnecting the motor
- Do not use holding torque/detent torque of motor as fail-safe brake
- Use an Electromate® recommended stepper drive with your step motor to ensure optimal performance
