The TMR-075-16-001-2 limited angle torque motor utilizes a toroidally wound, stationary coil assembly with a two-pole permanent magnet rotor to generate torque. The rare earth permanent magnet rotor always has an even number of poles, with two to six poles. The maximum angular excursion with a two-pole rotor is 180º, but the torque will drop […]

SDP/SI adds integrated motors to simplify motion system design
Stock Drive Products/Sterling Instrument (SDP/SI) has launched a series of Integrated Motors to simplify motion system design. Replacing multiple components with a compact all-in-one motor and electronics package, Integrated Motors simplify motion system design while providing many advantages. “Doing speed, position and torque closed-loop control with separate brushless motor and driver/controller technologies can be challenging,” […]
How to calculate continuous and peak torque values for servo applications
One of the most important tools for sizing a servo motor is the motor’s torque-speed curve, which shows the combinations of torque and speed that the motor can produce in two operating zones — continuous operation and peak, or intermittent, operation. To prevent thermal overload of the motor — and the drive — it’s important to […]
What is a direct drive in the context of motion applications?
In the most common motor-driven systems, the motor is coupled to the load being moved by a mechanical transmission element — a belt, chain, rack and pinion, ball or lead screw, or even simply a gearbox. But some linear and rotary motion systems do away with mechanical transmission elements and couple the load directly to […]
Servo motors with high accuracy, smoothness of motion for automated precision processes
PRHD2 high-performance permanent magnet synchronous servo motors from Servotronix Motion Control are suitable for automated precision processes such as robotic manufacturing, machine tooling, and electronics assembly.

Successful lab experiments start with the right pipette motor
For medical lab applications, motor selection is integral to an electronic pipette’s accuracy and precision. Valentin Raschke Application Engineer Portescap Laboratory automation has always been a great fit for linear motion. Within certain laboratory devices, precision is required for moving samples into position, adding reagents, and withdrawing samples. Advancements in the linear force and speed […]
New explosion-proof AC and BLDC gearmotors and motors for hazardous locations
Bodine Electric Company introduces forty new Ex-Proof AC and BLDC gearmotors and four new motors, that are UL listed for use in environments where ignitable concentrations of flammable gases, vapors or liquids are likely to exist under normal operating conditions. These new CI/D1 geared motors combine Bodine’s high-performance type 34R6 (inverter-duty AC) or type 34B6 […]
New family of servo systems from AutomationDirect
SureServo2 servo systems, built from motor, drive, I/O breakout module, and cable set components, are now available from AutomationDirect. The SureServo2 offering includes high-powered systems (up to 15 kW), wide input power options (110 Vac or 220 Vac in single or three phase), and a host of additional hardware and software features. The built-in motion […]
What are the performance benefits of 5-phase stepper motors?
Stepper motors are often categorized by the number of phases in their construction, with 2-phase and 5-phase versions being common designs. And although 2-phase versions are more widely adopted, 5-phase stepper motors offer performance advantages that make them the preferred choice in some applications. The basic construction of a hybrid stepper motor includes two rotor […]
New Class I, Division 2 AC gearmotors from Bodine Electric
Bodine Electric Company introduces twenty new AC gearmotors that are UL listed for use in environments where flammable gases or vapors may accidentally be spilled or leak into the operating area. These integral geared motors combine Bodine’s high-performance type 34R variable- or fixed-speed AC motors with a parallel shaft type FX gearhead. Typical applications include […]
