The functioning of a sensorless motor is easy to understand. In all motors, the relation of back-EMF and torque versus rotor position is the same. Zero crossing of the voltage induced in the non-energised winding corresponds to the position of maximum torque generated by the two energized phas...
The most advanced closed-loop stepper control method is to operate the motor as a two-phase brushless (BLDC) motor. (Note that many stepper motors have two phases offset by 90° whereas brushless dc motors have three phases offset by 120°.) This method is referred to as servo stepper or...
Stepper motors are so named because each pulse of electricity turns the motor one step. Stepper motors are controlled by a driver, which sends the pulses into the motor causing it to turn. The number of pulses the motor turns is equal to the number of pulses fed into the driver. The mot...
(EtherNet/IP, Modbus-TCP, & Profinet). We've reduced total system costs and simplified installation because you only have to purchase one product versus a separate controller, drive, and motor. Plus, programming & configuration is streamlined because it uses standard commands through your PLC's ...
Figure 3: Servo Motor Torque versus Speed Curves: 3436D@48VDC and 3421P@75VDC The smaller motor running at 75 VDC has almost the identical peak power as the larger motor running at 48 VDC (it has lower peak torque, but higher speed). The smaller 3421P motor running at 75 VDC has ...
What are the advantages of using a brushless motor versus a brush style motor? No brush noise, efficient, durable, robust, easy to cool Linear current/torque Synchronous speed control Position and Speed Servo (open/closed loop) Customizable Performance ...
+ Drive + Controller into a single product that interfaces to your PLC or PAC over the network (EtherNet/IP, Modbus-TCP, and Profinet). We've reduced total system costs and simplified installation because you only have to purchase one product versus a separate controller, drive, and motor. ...
AMCI's SMD34K incorporates a Stepper Motor + Drive + Controller into a single product that interfaces to your PLC or PAC over the EtherCAT network. We've reduced total system costs and simplified installation because you only have to purchase one product versus a separate controller, ...
