Detailed Explanation of Selection Calculation

1. Core formula and steps for selection

(1) Basic parameter collection

Key parameters such as load mass (mW), worktable mass (mT), motor rotor mass (mM), target speed (v), acceleration time (t ₐ), deceleration time (td), friction coefficient (μ), and external force (F) need to be clearly defined.

(2) Core Strength Calculation

Steady state thrust (force required for uniform load operation):

F L=9.8×M×(m W+m T+m M)+F

Acceleration thrust (force required during load acceleration phase):

F P=(m W+m T+m M)× t onev+F L

Deceleration thrust (force required during load deceleration phase):

F S=(m W+m T+m M)× t dv−F L

Effective thrust (average thrust during cyclic operation):

F RMS= tF P two⋅t one+F L two⋅t C+F S two⋅t d(t is the total time of the cycle, t_C is the uniform speed time)

(3) Selection verification criteria

Acceleration thrust ≤ maximum motor thrust × 0.9;

Deceleration thrust ≤ maximum motor thrust × 0.9;

Effective thrust ≤ motor rated thrust × 0.9;

The total load mass (mW+mT) is ≤ the maximum allowable load of the motor (to be combined with the configuration of the braking resistor).

2. Selection Example (Taking SGLGW-60A253C as an Example)

Known conditions: load mass of 1kg, worktable mass of 2kg, rotor mass of 0.82kg, speed of 2m/s, acceleration time of 0.02s, friction coefficient of 0.2, external force of 0N;

Calculation results: Steady state thrust of 7.5N, acceleration thrust of 389.5N, effective thrust of 108.3N;

Verification: The maximum thrust of the motor is 440N × 0.9=396N (≥ 389.5N), and the rated thrust is 140N × 0.9=126N (≥ 108.3N). The selection is qualified.

Installation specifications (mechanical+electrical)

1. Mechanical installation specifications

(1) Installation environment requirements

Environmental restrictions: Indoor use, no corrosive gases (such as hydrogen sulfide), explosive gases, no strong magnetic field interference (away from electromagnets and large transformers);

Strong magnetic protection: The magnetic track contains neodymium iron boron strong permanent magnets and should be kept away from electronic medical equipment such as pacemakers (safety distance ≥ 1m). Non magnetic tools (brass, stainless steel) should be used during operation to avoid magnetic substances (nails, wrenches) from approaching and causing compression injuries;
