New High-torque, high-performance brushless servomotors from ElectroCraft

The RapidPower Plus Series of high-torque, high-performance NEMA 23 frame brushless servomotors from ElectroCraft Inc. are designed for higher-precision applications.  The low-vibration BLDC motors use M-8 ceramic and rare-earth neodymium magnets, to provide quick acceleration and consistent speed (up to 15,000 rpm).  Sealed ball bearings and reduced torque ripple from skewed magetization also ensure a … Continue reading New High-torque, high-performance brushless servomotors from ElectroCraft

PMDC Motor Linear Actuators from ElectroCraft

This 1.5-in PMDC linear actuator is one of ElectroCraft’s innovative permanent magnet DC motor designs available in both a linear actuator with axial leadscrew or a leadscrew motor with rotating leadscrew. This DC motor does not require expensive motor drives. Performance is proportional to input voltage and can be tuned by regulating input voltage. Based … Continue reading PMDC Motor Linear Actuators from ElectroCraft

Improving High-Speed Performance of Hybrid Stepper Motors

Experts pretty much agree that motor torque is proportional to motor current and motor speed is proportional to drive supply voltage, but do you know when this might not be true?  This paper reviews the performance of constant current stepper drive across the motor speed range and the impact of the motor’s inductance, back-EMF and … Continue reading Improving High-Speed Performance of Hybrid Stepper Motors
