Three ways to reduce heat when operating a step motor
Reduce motor heat by reducing idle and running current — or switch to closed-loop control. Eric Rice | Applied Motion Products Step motors are widely used motion-control devices because of their simple setup and accurate positioning with an open-loop configuration. But problems associated with heat generation can arise. That’s because the drive that powers an […]
New series of stepper drives for ac-powered applications from Applied Motion Products
Applied Motion Products expands its family of STR Stepper Drives with two new ac-powered units for use in industrial applications powered by ac supply voltages. Offering the benefits of low noise, smooth motion, and high torque over wide speed ranges, the STRAC Stepper Drives bring high-performance motion control to basic step and direction applications. Units […]
Stepper drives: What’s the difference between an L/R drive and a chopper drive?
There are two fundamental types of stepper drives: L/R drives and chopper drives. L/R stepper drives are also referred to as “constant voltage” drives, because they supply constant voltage to the motor windings. The current produced in the windings depends on the motor’s time constant, which is the relationship between its inductance and resistance (L/R). The […]

Absolute type AZ Series stepper motor driver with EtherCAT from Oriental Motor
Oriental Motor now sells a DC-input AZ Series Multi-Axis Drivers with built-in EtherCAT communications. These are based on closed-loop absolute-type AZ Series driver. The AZ Series Multi-Axis Drivers with EtherCAT is a space saving, DC input, multi-axes controller and driver designed for applications demanding 2 or more axis of control and integrating EtherCAT communications from […]
Controller-drivers steer stepper-motor-driven sample-transfer machine
Gatan Inc. makes specimen-preparation equipment and recently built an alpha prototype of a new machine. The iPrep prototype mounts to a scanning electron microscope (SEM) and shuttles samples back and forth between a processing chamber and SEM receiving dock. Within the processing chamber, two broad-beam ion guns polish samples. The iPrep’s automated transfer mechanism allows […]
New AC-powered STR stepper drives from Applied Motion Products
Applied Motion Products, Inc. now sells an expanded line of STR Stepper Drives with the release of new drives for use in AC powered applications. STR stepper drives are designed for smooth motion and high torque over a wide speed range, bringing high performance motion control to basic step and direction applications. Two new AC […]
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 […]
IDEC releases line of stepper motion control products
IDEC Corp. introduces 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 […]
