maxon motor has now expanded its line of EPOS modular digital-positioning controllers. These drive+controllers are suitable for controlling permanent-magnet motors (including encoders) with 1 to 1,050 W of continuous output power. The wide range of operating modes (as well as various command interfaces) make it work in different drive systems employed in automation technology and […]
High-performance sensorless control from maxon motor
Now, a new control option from maxon motor has compact wiring and slim design. Called the HPSC, this sensorless speed and torque control allows field-oriented control (FOC) of brushless motors. Such control is without sensors from full stop to full speed under load. This HPSC uses a sophisticated signal-injection algorithm which precisely determines the rotor […]
Exoskeleton joint actuator is reliable, powerful, efficient
Maxon Motor has developed an exoskeleton drive for use in robotic limbs. This complete joint actuation unit consists of a pancake brushless DC motor with inertia optimized rotor. Also included is an internal high resolution encoder, planetary gearhead with absolute encoder and a position controller with CAN and RS232 interface. Fitting absolute encoder directly at […]
Brushless (electronically commutated or EC) motor basics video: Simple commutation to field-oriented control
Brushless motors are any permanent-magnet motors, switched-reluctance motors, or induction motors that omit the use of commutator and brushes for commutation. But one motor type is usually implied when engineers use the term brushless motor — the permanent-magnet design. Also called electronically commutated or EC motors, these don’t suffer from brush wear or arcing … […]
