Lin Engineering now sells 106 Series hybrid stepper motors with a step angle of 3.46° and 104 steps per revolution. The compact motors are just 16 mm wide but deliver to 1.85 oz-in. holding torque. That equates to quadruple the holding torque of can-stack PM steppers … and in fact, the 106 Series hybrid stepper […]

Hybrid linear stepper motors: Operation and applications
Like servo motors, stepper motors are available in both rotary and linear designs. When an application requires force (rather than torque) output and can operate in open loop control, a linear stepper motor is often the preferred solution. Although linear stepper motors are available in both variable reluctance and hybrid designs, the more common version is […]
How do switched reluctance motors differ from stepper motors?
Switched reluctance motors operate by switching currents in the stator windings in response to changes in the magnetic circuit formed by the rotor and stator. The stator of a switched reluctance motor contains windings, similar to a brushless DC motor, but the rotor is simply made of steel that is shaped into salient poles, with […]
Applied Motion partners with HEIDENHAIN, RENCO on new StepSERVO integrated motors
HEIDENHAIN CORPORATION has partnered with Applied Motion Products, Inc. in the development of their StepSERVO™ integrated motors for high performance motion control applications. Using HEIDENHAIN’s RENCO brand RCML 15 rotary encoder inside, StepSERVO offers the next evolution in step motor technology, combining the high torque capabilities of step motors with the closed loop dynamic control […]
IP65 integrated stepper motors from Applied Motion
SWM integrated steppers are IP65 rated drive+motor units, fusing step motor and drive components into a single splashproof and dustproof device. This space—saving design eliminates wiring and saves on cost over conventional motor and drive solutions. The SWM24 integrated steppers combine high torque NEMA 24 step motors with a sophisticated, 6.0 A/phase (peak-of-sine) step motor […]
IDEC releases line of stepper motion-control products
IDEC Corp. now sells a line of motion-control stepper products in conjunction with Advanced Micro Controls Inc. (AMCI), an established developer of motion control systems. This AMCI by IDEC product line includes controllers, stepper motors, an integrated controller/drive, an integrated drive/stepper motor, and an integrated controller/drive/stepper motor. When combined with an IDEC FC6A PLC and its […]
What stepper motor type is best for high torque?
Stepper motors are commonly recognized for their holding torque, which allows them to hold a load at standstill. But for dynamic movements, it’s the motor’s pull-out torque that is important. Pull-out torque is the amount of torque that a stepper motor can produce while it is rotating, without causing it to lose steps. A stepper motor’s ability to generate […]
Why is the electrical time constant important for stepper motors?
Motor windings have a property referred to as inductance, which is a resistance to any change in the electrical current through the winding. The result of inductance is the production of back EMF to oppose the change in current. Where: Eb = back EMF (volts) L = inductance (H, or Ohm-s) dI/dt = rate of […]
Low-cost tin-can stepper motors from Nippon Pulse feature high torque and compact size
The PF/PFC series tin-can stepping motors are conventional magnet-driven rotary stepper motors with a permanent magnet in their rotor core. Rotating in proportion to the number of pulses sent to the motor, the stepper motor is frequency synchronized and can change speed depending on the frequency of the pulse signal. Because of its high torque […]
FAQ: What is microstepping?
Microstepping is driving a stepper motor at less the one full step per movement. Under usual operating conditions, a stepper motor operates by turning one full step with every pulse of current. Microstepping allows a motor to make far finer steps. This done by having the controller and drive send the proper kinds of current […]
