 The figure on the right shows the points of operation determined by the effective torque and 

average rotational speed calculated above, plotted on the graph of operable range of HMAC08, 
exceeding the continuous motion range. The conclusion is that this motor cannot be operated 
continuously under these conditions. Accordingly,   

 

the operation pattern 

load (possible reduction)

 

motor model No. 

 
etc., must be reevaluated. 

 

 

The following formula is a modified version 
of the formula for effective torque. By 
applying the value of allowable continuous 
torque to T

m

 in this formula, the allowable 

cycle time can be calculated.

Apply the following: T

 = 1.38 Nm, T

r

d

 = 1.29 Nm, T

m

 = 0.52 Nm, t

= 0.099 s, t

r

= 0.035 

s, t

= 0.080 s. Then, the following equation is obtained: 

 

t = (1.38

x 0.099 + 1.29

2

 x 0.080)/ 0.52

2

 = 1.19 s 

Based on the result, setting the cycle time to 1.2 seconds or more to provide a longer stop time 
gives T

m

 = 0.52 Nm or less, thereby permitting continuous operation within the rated torque. 

 

 

 

  The aforementioned continuous motion range represents an allowable range where the 

motor installed on a specified aluminum radiation plate is operated under natural air 
cooling. If the radiation area of the mounting member is small or heat conduction of the 
material is poor, adjust the operating conditions to keep the rise in the motor's ambient 
temperature to 40 K or less as a guide.
