Selection and awning motor sizing. Retrofit an awning motor - what you should consider

You have already installed an awning and would like to retrofit a motor? When selecting the suitable motor, you should first check which type of control you want. heicko offers numerous control options, such as direct controls via push button switch, radio emitters with or without time control, sun and wind sensors as well as APP controlled Smart Home variants.

1. Direct control with push-button switch - For awning motors without built-in radio receivers:

a) Without emergency hand crank function on the motor's head:

We recommend our ER or HR series [link to B24]

b) With emergency hand crank function on the motor's head:

We recommend our ERN series (emergency crank function in case of power failure - crank your awning when the power has dropped during thunderstorms.)


2. Radio emitter control - awning motor with built-in radio receiver:

a) Without emergency hand crank function on the motor's head:

We recommend our ERF or HRF series [link to B24]

b) With emergency hand crank function on the motor's head:

We recommend our ERFN series (emergency crank function in case of power failure - crank your awning when the power has dropped during thunderstorms.)


Notes for the assembly of awnings

Awnings are used to cover terraces and balconies and in particular to provide protection against solar radiation. A distinction is made between drop arm awnings, articulated arm awnings, cassette awnings and other open awning systems. The operation is similar, but handling and assembly are different.

Almost any awning can be equipped with a tubular motor, which is inserted into the awning shaft. In just a short time the awning can be moved in and out automatically. (Make sure that the hinged arms of the awning are either extended or fixed, as they are under high tension and as a result there is a high risk of injury.)

Shaft diameter of the awning:

Check which shaft diameter (diameter of the groove tube) your awning has. Frequently used round shaft diameters are 63 mm, 70 mm, 78 mm and 85 mm. When purchasing a motor, please make sure that you order the correct awning adapter set. We have a wide range are happy to advise you.

Awnings can weigh from about 40 to over 100 kilograms and require professional installation (see DIN-EN 13561), so that they do not break out of the wall, ceiling or rafter support in strong winds. Motorized awnings can optionally be equipped with control sensors (item no. HR1300-WIND-G2), which automatically retract the awnings in case of high wind loads or rain.[link to B24 and picture]

Strength of the awning motor:

The question of how strong an awning motor should be is influenced by several factors:

  • The number of articulated arms
  • Spring force of the arms
  • Width of the awning
  • Outreach of the awning
  • Diameter of the round shaft
  • Tilt angle
  • and similar

Unfortunately general valid statements are therefore not possible. Our guidelines:

Example: Shaft diameter 78 mm, tilt angle 30°
Number of articulated arms  - Awning(Width x Outreach) - Strength in Nm in m

2 3 x 2 m >/=28 Nm (Spring force [kg/Arm]=30)

2 6 x 3 m >/= 29 Nm (Spring force [kg/Arm]=30)

2 7 x 4 m >/= 35 Nm (Spring force [kg/Arm]=35)

2 8 x 3 m >/= 30 Nm (Spring force [kg/Arm]=30)

2 8 x 3,5 m >/= 34 Nm (Spring force [kg/Arm]=35)

4 8 x 4 m >/= 66 Nm (Spring force [kg/Arm]=35)

4 10 x 4 m >/= 65 Nm (Spring force [kg/Arm]=35)

4 12 x 5 m >/= 69 Nm (Spring force [kg/Arm]=35)

6 12 x 5 m >/= 98 Nm (Spring force [kg/Arm]=35)
