Calculation Examples

---

When selecting a brake, certain parameters are used. These parameters are listed below. The required torque is calculated, and the brake size is selected. In cases where the operating frequency is high, the thermal load is calculated and checked using the "Friction Energy and Operating Frequency" diagram.

If Motor Power and Speed Are Known M_d:

	Md[Nm] : Torque
	N [kW] : Power
	n [rpm] : Rotational speed

or

	Md[Nm] : Torque
	P [hp] : Power
	n [rpm] : Rotational speed

When Torque M_d Is Multiplied by Safety Factor S_K, It Becomes M_G:

	MG [Nm] : Required torque
	N [kW] : Power
	n [rpm] : Rotational speed
	SK : Safety factor
Example Calculation: Assume a motor power of 3 kW and a rotational speed of 1500 rpm. If we take the safety factor as 2: According to this torque value (38.2 Nm), the DYF04 brake size is selected from the brake selection table.

or

	MG [Nm] : Required torque
	P [hp] : Power
	n [rpm] : Rotational speed
	SK : Safety factor
	MK [Nm] : Brake torque
Example Calculation: Assume a motor power of 4 hp and a rotational speed of 1500 rpm. If we take the safety factor as 2: According to this torque value (38.2 Nm), the DYF04 brake size is selected from the brake selection table.

Thermal Load

	QT [J] : Friction energy
	J [kgm²] : Mass moment of inertia
	n [rpm] : Rotational speed
	Mb [Nm] : Static load torque
	MK [Nm] : Brake torque
