AC/DC MOTORS & DRIVES ENGINEERING REFERENCE

In the wide range of Dunkermotoren products, you will find a suitable drive for almost any requirement in powers ranging from 1 to 500 Watt. The following points should be taken into account when selecting motors and gearboxes

  • Which type of operation is required (continuous, intermittent or periodic operation)?
  • What is the working life expected of the motor?
  • What torque and speeds are required?
  • How much space is available for the motor?
  • How high is the available voltage? DC or AC?
  • Are there special environmental conditions (temperature, humidity, vibration, …)?
  • To what degree can heat from the motor be disposed of?
  • Are there exceptional axial and radial shaft loads to consider?
  • What demands are made of the motor control electronics?
  • Is the motor to be controlled online via a bus system?
  • Do you need a brake, an encoder or a non-reversing device?

When laying out a suitable motor, determining the required torque plays a decisive role in avoiding thermal overload of the motor in service.

In the assembly of a drive system consisting of motor and control electronics, it is important to ensure that permissible values for the motor are not exceeded by outputs from the electronics. Depending on the speed of rotation required, a motor or a motorgearbox combination may be selected. The choice of a reduction gearbox will largely depend on the recommended maximum torque in continuous operation. For intermittent duty, loading above the rated torque is possible.

When choosing a motor after deciding on the gearbox, the following applies:

Mmotor = Mgearbox / (i x ?)
